Why Choose GTTS

Embedded SIM (eSIM) is just a SIM card gone digital, so you don’t have to wait for a physical SIM. Just download your eSIM over Wi-Fi and connect to the T-Mobile network in minutes! 

To determine if your device is compatible with T-Mobile Prepaid, you should use the official T-Mobile IMEI Compatibility Checker tool. This is the most reliable method as it checks the device’s unique identifier against T-Mobile’s network requirements.Steps to Check Compatibility1. Find your IMEI number:

• Dial *#06# on your phone’s keypad to display the 15-digit IMEI number.
• Alternatively, find it in your phone’s settings (e.g., for Android: Settings > About phone > IMEI; for iPhone: Settings > General > About).

2. Use the online checker:

• Go to the T-Mobile Prepaid Bring Your Own Phone page.
• Enter your device’s IMEI number in the provided field.
• Select Check phone to see the results.

For your phone to work optimally on the T-Mobile network, it generally needs to be:

• Unlocked: The device must be unlocked from its previous carrier’s network (meaning it’s not tied to a specific service provider contract).
• GSM Compatible: T-Mobile is a GSM carrier, so your phone needs to support GSM and LTE technologies.
• VoLTE Compatible: The device must support T-Mobile’s implementation of Voice over LTE (VoLTE) for clear calls and to prevent dropped calls.
• Band Support: For the best coverage, the phone should support T-Mobile’s key frequency bands, which include Band 2, Band 4, Band 12, and for the best 5G experience, Band 71 and others.

There’s a few ways to set up your eSIM:

• During the initial setup, you’ll be prompted to activate an eSIM or transfer one from an existing Phone.
• If you’ve already set up your Phone and are connected to Wi-Fi, your Phone will prompt you when the T-mobile Plan is ready to be installed.
• Didn’t get a prompt or chose to activate later? You can activate your eSIM from the device Settings > Cellular (iphone) or  Settings > Connections > SIM manager > Add eSIM (samsung).
• FOR ESIM Set up via QR code: Connect to Wi-Fi and scan the QR code. Check in Settings > Network & Internet > Mobile Network for most Androids.

Yes, you can use your local SIM and eSIM simultaneously and  you can also use multiple eSIMs on a single device, but the specifics of how many you can store and how many can be active at the same time depend on your device model. Most devices support one physical SIM and one eSIM simultaneously, while some modern phones can use two eSIMs at once. This is useful for travel, separating personal and work lines, or managing different data plans. 

No, you do not need to reinstall an eSIM to switch between profiles that are already installed on your device. You can simply select which profile you want to use from your phone’s settings, as most modern devices allow you to store multiple eSIMs and switch between them at any time. You only need to reinstall an eSIM if you are transferring it to a new device.How to switch between installed eSIMs

• iOS: Go to Settings > Cellular and tap on the line you want to use.
• Android: Go to Settings > Network & internet > SIMs and toggle the eSIM you want to activate.

When you need to reinstall an eSIM

• Transferring to a new phone: You must remove the eSIM from your old device and then install it on the new one using the original QR code or or our 24/7 email customer support.
• If you deleted it: If you previously deleted a profile, you will need to reinstall it using the original QR code or our 24/7 email customer support.

Yes, a T-Mobile eSIM allows you to make calls and send SMS, just like a physical SIM card. The functionality is identical, provided the eSIM includes a voice and text plan with a phone number, which is standard for major carriers like T-Mobile. You can use the eSIM for calls and texts, and data. 

Best practice: Purchase and install your eSIM at home—where the internet is stable—then activate it when you land. Some countries restrict access to eSIM provider websites once you’re in-country, so pre-departure setup ensures you’re connected on arrival.

To make sure your eSIM is activated given that it was already set up at home before your travel, upon arrival make sure to turn off your device for a few minutes and turn it back on again for the eSIM to connect to the nearest cellular tower.

If eSIM is not installed prior to arrival, please make sure to use a strong WIFI to receive a prompt to install it.
