Are you a T-Mobile iPhone user considering switching to AT&T, but unsure if your device will be compatible? Or perhaps you’ve purchased a used T-Mobile iPhone and want to know if you can use it on the AT&T network? In this article, we’ll delve into the world of carrier compatibility, unlocking, and frequency bands to provide you with a comprehensive answer.
Understanding Carrier Compatibility
Carrier compatibility is a crucial factor to consider when switching from one network to another. In the United States, there are four major carriers: Verizon, AT&T, T-Mobile, and Sprint. Each carrier uses a specific frequency band to provide service to its customers. The frequency band is the range of frequencies used by a carrier to transmit data, voice, and text messages.
T-Mobile and AT&T use different frequency bands, which can affect compatibility. T-Mobile uses a combination of GSM (Global System for Mobile Communications), UMTS (Universal Mobile Telecommunications System), and LTE (Long-Term Evolution) frequency bands, while AT&T uses GSM, UMTS, and LTE frequency bands as well. However, the specific frequency bands used by each carrier differ.
T-Mobile Frequency Bands
T-Mobile uses the following frequency bands:
- GSM: 1900 MHz (PCS)
- UMTS: 1700/2100 MHz (AWS)
- LTE: 1700/2100 MHz (AWS), 1900 MHz (PCS), 2500 MHz (BRS), 2600 MHz (IMT-E)
AT&T Frequency Bands
AT&T uses the following frequency bands:
- GSM: 850 MHz (Cellular), 1900 MHz (PCS)
- UMTS: 850 MHz (Cellular), 1900 MHz (PCS)
- LTE: 700 MHz (Band 12), 850 MHz (Band 5), 1700/2100 MHz (Band 4), 1900 MHz (Band 2), 2300 MHz (Band 30)
Unlocking Your T-Mobile IPhone
To use your T-Mobile iPhone on the AT&T network, you’ll need to unlock it first. Unlocking your iPhone allows you to use it on any carrier that supports the same frequency bands. There are two types of unlocking: hardware unlocking and software unlocking.
Hardware unlocking involves modifying the iPhone’s hardware to accept different carrier SIM cards. This method is not recommended, as it can void your warranty and potentially damage your device.
Software unlocking, on the other hand, involves using a software tool to unlock your iPhone. This method is safer and more reliable. You can unlock your T-Mobile iPhone through the carrier’s website or by contacting their customer support.
How To Unlock Your T-Mobile IPhone

Alternatively, you can contact T-Mobile customer support and request an unlock. They will guide you through the process and provide you with an unlock code.
Using Your T-Mobile IPhone On AT&T
Once your T-Mobile iPhone is unlocked, you can use it on the AT&T network. However, you’ll need to ensure that your device supports the same frequency bands used by AT&T.
As mentioned earlier, T-Mobile and AT&T use different frequency bands. However, most modern iPhones support multiple frequency bands, making them compatible with different carriers.

Can I Use A T-Mobile IPhone On AT&T’s Network?
You can use a T-Mobile iPhone on AT&T’s network, but there are some conditions that apply. The iPhone must be unlocked, which means it’s not tied to any specific carrier. If your iPhone is locked to T-Mobile, you’ll need to contact them to request an unlock. Additionally, the iPhone must support AT&T’s frequency bands.
Once you’ve met these conditions, you can insert an AT&T SIM card into your iPhone and it should work on their network. However, you may need to configure the APN settings to get data working properly. You can find the APN settings for AT&T on their website or by contacting their customer support.
How Do I Unlock My T-Mobile IPhone?
To unlock your T-Mobile iPhone, you’ll need to contact T-Mobile’s customer support and request an unlock. They’ll ask for your iPhone’s IMEI number, which you can find in the Settings app under “General” > “About.” T-Mobile may have certain requirements or restrictions for unlocking, such as requiring your account to be in good standing or having a certain amount of time left on your contract.
Once T-Mobile has processed your unlock request, they’ll send you an email with instructions on how to complete the unlock process. This usually involves connecting your iPhone to iTunes and restoring it to its factory settings. After the unlock is complete, your iPhone will be free to use on any carrier that supports its frequency bands.
Will I Be Able To Get 5G On AT&T’s Network With My T-Mobile IPhone?
It depends on the specific iPhone model you have and the frequency bands it supports. AT&T uses a combination of low-band, mid-band, and high-band frequencies for its 5G network. If your T-Mobile iPhone supports these frequencies, you should be able to get 5G on AT&T’s network. However, if your iPhone only supports T-Mobile’s specific 5G frequencies, you may not be able to get 5G on AT&T’s network.
You can check the specifications of your iPhone model to see which frequency bands it supports. You can also contact AT&T’s customer support to ask about their 5G coverage and which frequencies they use in your area.

As long as your iPhone is connected to a Wi-Fi network and you have a compatible plan with AT&T, you should be able to use Wi-Fi calling.
However, you may need to configure the Wi-Fi calling settings on your iPhone to work with AT&T’s network. You can do this by going to the Settings app and selecting “Phone” > “Wi-Fi Calling.” From there, you can toggle Wi-Fi calling on and off and configure other settings as needed.
