What is Personal Mobile Banking?

First Interstate Bank's Personal Mobile Banking services gives you quick, secure access to your First Interstate Bank personal account information whenever you need it, right from your mobile device.


What Personal Mobile Banking services are offered?

Mobile Banking consists of three separate - but complementary - services. Many customers choose to use more than one method based on their needs.

Mobile Text Banking: Mobile Text Banking gives you the ability to send specific text commands to a shortcode (a five or six digit phone number) to obtain account balances, view account transaction history or perform account transfers. First Interstate Bank's short code is TXTFIB (898342).

Mobile Web Banking: Mobile Web Banking is a website accessed through your mobile device; this website is optimized for mobile device browser viewing. It contains most of the same features available for Personal Online Banking, only formatted for viewing on a small screen mobile browser.

Mobile App Banking: Mobile App Banking is a mobile application that is downloaded to your mobile device. Once installed, the First Interstate Bank Personal Mobile App provides a unique banking experience for iPhone® and Android™ and BlackBerry® users. It enables you to take part in many of the features available with I-Bank Personal Online Banking today as well as our new Mobile Check Deposit feature available via our iPhone and Android apps.


What accounts can I access from Personal Mobile Banking?

Personal Mobile Banking provides access to the same accounts that are accessible through I-Bank Personal Online Banking including your checking and savings accounts, Certificates of Deposit, and Loans.


What do I need to begin using Personal Mobile Banking?

In order to access First Interstate Bank's Personal Mobile Banking services, you must be a current First Interstate Bank I-Bank Personal Online Banking user and have a mobile device with a text message and/or data plan. If you do not have a text message and/or data plan, or are unsure if you do, please contact your wireless carrier for details.


How do I enroll for Personal Mobile Banking?

You enroll for First Interstate Bank's Personal Mobile Banking services by logging into I-Bank Personal Online Banking. Then, click the "Mobile Banking/Alerts" tab to enroll.


I just enrolled in Personal Online Banking and am attempting to sign-up for Personal Mobile Banking. However, I keep receiving an error. Why is this?

Once you have enrolled in Personal Online Banking, it takes a nightly update of the system before Personal Mobile Banking enrollment is available. Please try enrolling in Personal Mobile Banking the next day. If you continue to receive an error, please contact Customer Support.


Will I need a new Access ID and Password to use Personal Mobile Banking?

No, you will use the same login credentials you use when you login to I-Bank Personal Online Banking. Before you can login to Personal Mobile Banking, you must first enroll for Personal Mobile Banking through I-Bank Personal Online Banking.


Is there a cost for using Personal Mobile Banking?

There is no fee to access First Interstate Bank's Personal Mobile Banking Services. Standard transaction fees apply. If you choose to use our new Mobile Check Deposit option, there is a per item convenience fee associated with that service. Wireless carrier message and data rates may apply. These include fees your wireless carrier may charge you for data usage and text messaging services. Check with your wireless carrier for details regarding your specific wireless plan and any data usage or text messaging charges that may apply.


Will I have the same functionality with Personal Mobile Banking as I do with Personal Online Banking?

You will be able to do many of the same functions using Personal Mobile Banking including viewing accounts, viewing transactions, transferring funds, and paying bills. However, you will still need to use I-Bank, Personal Online Banking for other functions such as managing bill payment payees, changing your password, and managing your Personal Mobile Banking preferences.


Is Personal Mobile Banking secure?

First Interstate Bank is very concerned about the safety and privacy of your information and committed to security. To ensure the security of your account information, a number of features have been built into the Personal Mobile Banking services:

Registration Process - A unique verification code is required to verify your mobile device's phone number. This also verifies that you are the one in control of your mobile device. This code associates your mobile device's phone number with your Personal Mobile Banking account.

No Identifiable Information - Texts or Alerts from First Interstate Bank never include any personally identifiable information, such as your full account number, PIN, email address, or mobile number. Your Access ID and Password will never be included in any of the text messages or Alerts you receive from First Interstate Bank.

Secure Login - Personal Mobile Banking via Mobile Web and Mobile App require a secure login for access. No one is able to access your account information without knowing your unique username and password.

Data Encryption - For your protection, only limited information (such as your account nicknames and cached balances) is stored locally on your mobile device. All of your account data resides at your bank - just as with I-Bank Personal Online Banking. All data placed into local storage on the mobile device is encrypted before it is stored - and it is only accessible with your PIN. This ensures that if your mobile device is lost or stolen, the data stored by the mobile application in local storage is unreadable.


Do I need to secure my phone?

First Interstate Bank recommends that you lock your phone using a PIN code or password when it is not in use; this secures any information on your device. We also recommend that you do not store your password on your mobile device.


Is account information retained in my phone?

Information from your mobile banking session is not retained as long as you log out after each First Interstate Bank Personal Mobile Banking session. Additionally, First Interstate Bank's Personal Mobile Banking masks account numbers that are displayed on your mobile device. We also recommend that you do not store your password on your mobile device.


What if my mobile phone or device is lost or stolen?

You should contact your wireless carrier immediately. You should also login to I-Bank Personal Online Banking and disable the mobile device within your Personal Mobile Banking preference.


To whom can I make bill payments in Personal Mobile Banking?

Bill payments can be made through Personal Mobile Banking to payees that have already been established within I-Bank Personal Online Banking. Specific payees can be disabled/enabled within the Personal Mobile Banking preferences center. New bill payment payees can only be added through I-Bank Personal Online Banking.


Can I use Personal Mobile Banking at any time?

Yes. Personal Mobile Banking is available 24 hours a day, 7 days a week, except during the bank's regular maintenance periods for your online and mobile services.


Personal Mobile Banking seems slow; why?

Your mobile device's connection speed may vary because of different wireless service providers, different data usage plans, and/or different geographic locations. If you experience a slow response, please check with your wireless service provider. You may also want to verify that you do not have other programs running in the background of your mobile device.


What types of transactions can I do through Personal Mobile Banking?

  • View account balances

  • Pay bills (must first be enrolled in I-Pay Personal Bill Payment)
  • Make deposits (via iPhone and Android Apps only)

From there you have the ability to configure the mobile account nicknames that are displayed in mobile banking.


Can I safely recycle or dispose of my mobile device if it has Personal Mobile Banking on it?

Although your information is not stored on your mobile device, we recommend you deleted any text messages, clear the browser history, and delete the Mobile Banking application from the device before recycling or disposing.


What happens if I change my mobile phone number or my wireless carrier?

If you change your mobile phone number or your wireless carrier and would like to continue using First Interstate Bank's Personal Mobile Banking, you must register your new mobile device within your Personal Mobile Banking preferences center. Login to I-Bank Personal Online Banking; click the "Mobile Banking/Alerts" tab, and click the "Phone" tab. Then, add and verify your new mobile device as well as delete your old mobile device.


What does the (P) in front of my transactions indicate?

This indicates the transaction is pending on the account.


Can I add bill pay Payees through Personal Mobile Banking?

No. Additional bill pay Payees must be added within I-Bank Personal Online Banking.


What are Nicknames?

To easily identify and differentiate between your accounts within Personal Mobile Banking, you are required to create account/ payee nicknames when activating accounts within Personal Mobile Banking to protect your private information. Each account/payee nickname must be unique, contain one to eight characters, and can include letters or numbers, but not spaces or special characters.

Important Tip: Choose short nicknames that are easy to type on your mobile device (eg: ch1, ch2, sav, mm, etc.).

Account nicknames within I-Bank Personal Online Banking will NOT default for Personal Mobile Banking. There are suggested default account/payee nicknames; however, you may change the nicknames within the Personal Mobile Banking preference center. Your Personal Mobile Banking nicknames will not replace the account nicknames defined within I-Bank Personal Online Banking.


I recently opened a new account and it is not showing in my Personal Mobile Banking?

For added security, you must enable new accounts within the Personal Mobile Banking preference center. Login to I-Bank Personal Online Banking, click the "Mobile Banking/Alerts" tab, click the "Accounts" tab, and then "Enable" the new account.


What is a default account?

The default account within Personal Mobile Banking will be the account that Text Banking commands will be applied to if an account nickname is not specified in the Text Banking command. You can change your default account by clicking on the "Accounts" tab within your Personal Mobile Banking preference center. For the best user experience, we recommend that your default account be your primary checking account.


What if someone else tries to use my mobile device?

If you are using Text Banking and if the other person knew where you banked as well as your bank's shortcode number, they could conceivably check your balance or transfer money from one of your accounts to another of your accounts. For extra privacy, regularly delete your old text messages.

If you are using Mobile Web Banking or Mobile App Banking, the other person would have to know your user name and password. Never share this information with anyone. Do NOT store this information on your mobile device and logout of your session when finished using Personal Mobile Banking.


Why can I only see balances for my First Interstate Bank credit cards and mortgages through Personal Mobile Banking?

At this time you can only view account balances for your First Interstate Bank credit cards and mortgages through Personal Mobile Banking. We will be adding payment and transaction details in future releases of Personal Mobile Banking.


How many incorrect login attempts will result in my Personal Mobile Banking account being locked?

After the third invalid attempt, you will be locked out of Personal Mobile Banking and I-Bank Personal Online Banking. Please contact Customer Support to have I-Bank Personal Online Banking reset. At that time, Personal Mobile Banking will automatically be reset because they use the same login credentials.


What happens to my confidential account information?

Personal Mobile Text Banking does not send any confidential security information about you or your accounts either to or from your mobile device. Similar to ATM receipts, full account numbers are never displayed. You are required to use account nicknames that don't include any digits from your account numbers.

Personal Mobile Web and Personal Mobile App Banking use encryption to keep your information secure and confidential. They do not store any confidential information on your mobile device.


What information is stored on my mobile device?

With Personal Mobile Text Banking, the only information "stored" on your mobile device are old text messages which do not contain any confidential information, but may include old balances (like an ATM receipt). You should delete your text messages regularly, just as you would destroy an ATM receipt.

With Personal Mobile Web and Personal Mobile App Banking, there is no confidential information stored on your mobile device. You should never use your mobile device's notepad or address book to store your login information.

Text Banking

What is Mobile Text Banking?

First Interstate Bank's Mobile Text Banking enables you to retrieve information and manage your bank accounts via text messaging from a mobile device.


What is a shortcode?

As a Mobile Text Banking user, you will use a special shortcode to communicate with the bank. Shortcodes are special telephone numbers, usually five or six digits long, that are used to send and receive text messages from mobile phones. They are often used for services such as television voting, ordering ring tones, charity donations, and mobile services. TXTFIB (898342) is First Interstate Bank's shortcode for communicating with you via Mobile Text Banking.


How do I know if my mobile device supports Text Banking?

The majority of all mobile devices in the U.S. now support text messages. To find out for certain if your mobile device supports text messages, contact your mobile service provider. Please be aware that some phone services apply charges for sending and receiving text messages. Review your phone service plan for any applicable texting charges.


Does Text Banking work with pre-paid mobile phone service plans?

Personal Text Banking will work with most pre-paid phone plans; however, there are some phone plans that do not support shortcodes.

The following pre-paid mobile service plans currently do not support short codes:

  • Mobile
  • Most Verizon MVNOs (e.g., MIGO)
  • TRACFONE®

How long does it take to get a response message via Text Banking?

You will usually receive a text message response in less than one minute. Exact timing will depend on your mobile service provider. If you have not received a message within 3-5 minutes, please retry your text command.


Are Text Banking commands case-sensitive?

No. Whether you type "BAL" or "bal" First Interstate Bank will send your account balance to you via text message.


Why can't I receive text messages from First Interstate Bank on my mobile phone? I am enrolled in Mobile Banking and have text messaging enabled on my phone.

You may have text messaging enabled on your mobile phone, but the use of shortcodes may be blocked by your mobile phone service provider. You must have shortcodes enabled to use First Interstate Bank's Mobile Text Banking. Please contact your mobile phone service provider to ensure they aren't blocking the use of shortcodes, and that your carrier supports the use of shortcodes.


Why are my results sent as multiple messages?

Each response you receive from First Interstate Bank may vary in size because all text messages are limited to 160 characters. Sometimes all of your account information cannot be sent in one message because it exceeds the 160 character limit. In this case, your account information will be sent in multiple messages - no more than five at a time.


What does it mean to see "1/2" on my text message response?

"1/2" means you are reading the first message in a series of two messages. It is labeled as "1/2" to ensure you will read your text messages in the correct order.


Why are the text messages out of order when multiple messages have been sent?

First Interstate Bank sends text messages to you in the order they are intended to be read. We will always clearly indicate the order the messages they are to be read (for example, "1/2" or "3/3"). Unfortunately, depending on your mobile provider, messages sometimes get mixed up on the way to your mobile phone.


What are the maximum number of results I can receive for each Text Banking inquiry?

You can receive up to five results per Text Banking inquiry.

How do I know if I can access Personal Mobile Banking through my mobile web browser?

If you have a mobile web browser and Internet access from your mobile phone, it's likely you can use Mobile Banking. Your mobile phone must support WAP (Wireless Application Protocol) 2.2 or higher, the international standard for applications using wireless communication. Most phones today support WAP. Display of your account information may vary depending on your phone. If you are using an older device that does not contain the required security features, you may need to upgrade to a newer device to use Personal Mobile Banking. You may incur and are responsible for charges assessed by your wireless provider as a result of this upgrade.


Can I bookmark the Personal Mobile Web site for future use?

Yes. To access Mobile Web Banking, enter https://mobile.firstinterstatebank.com in the URL field of your mobile phone's web browser. You may bookmark the URL on your first visit to easily access the website in subsequent visits.


How do I know if my phone is Internet-enabled?
