Bring Your Own Device - keep your number!

Millenicom can move your T-Mobile device to a Millenicom Plan over-the-air without needing a new SIM. Simply record the existing SIM’s ICCID number in the sign-up as well as your existing phone number if you like, and we immediately transfer the account. Here is how you find the ICCID number.

Sometimes an older T-Mobile device still requires a new SIM so if we are unable to activate your device over-the-air, we ship you a new SIM next-day-air. Here is how to replace your SIM.

If you have a PHONE from a different carrier, you may be able to use one of our SIMs

Check your phone’s compatibility:

Select the wireless carrier that you most recently used with your phone:

MENU

Enter the name of the device (e.g., iPhone 5S)

MENU

If you have a HOTSPOT, IPAD or TABLET from a different carrier, you may be able to use one of our SIMs

Select the wireless carrier that you most recently used with your device:

MENU

Enter the name of the device (e.g., Apple iPad Mini)

MENU

If your old phone or device is not available in the menu, then you will need to purchase one to use our service. There are very many reasonably priced devices on amazon.com, ebay.com, craigslist.com, etc. that it will be very easy to purchase one online.

For phones, we highly recommend any unlocked GSM smartphone
