Make sure 5G is supported by your network carrier

Just because you have the latest 5G smartphone doesn’t mean you will get 5G signals magically. 5G is still expanding, and there is only a limited number of areas that support fully 5G connectivity. So please check with your carrier partner regarding what areas they currently support 5G.

iPhone 13 series are designed to run 5G only on one sim card. If you are using a combination of two SIM (physical + eSIM), then both networks will automatically convert to 4G LTE. Currently, Apple does not support dual 5G connectivity.

Although when you use a 5G SIM card on your device, the network connectivity must automatically convert to 5G. But if it doesn’t, you can manually enable the 5G settings and enjoy superfast connectivity.

Open the Settings app and navigate to Cellular > Cellular Data Options.

Here choose 5G in the voice and data option.

Disable Roaming

Many networks do not allow 5G connectivity while you are roaming. So make sure you disable the roaming option. If you absolutely need it, you can enable 4G connectivity while roaming.

So Please connect with T-mobile via customer care call or by in-app chatbot. Once they activate 5G on your SIM card, you will receive new network configuration settings, and you can enjoy 5G on your iPhone 13 series.


So you see, when it comes to 5G connectivity, most of the issues tend to be software glitches which can be easily fixed by rebooting your device to update the carrier settings. But just because you enable 5G doesn’t mean you will start getting 5G connectivity, the area you line in must have 5G towers nearby. If none of the above methods works for you when T-Mobile 5G not working on iPhone 13 series, then it is possible that your device has hardware damage, and that’s the reason why it can’t pick 5G signals. IN that case, please connect with the nearest Apple store and get your device checked.
