Shutdown of 3G Networks in the USA | Welcome to Discoverflow

Shutdown of 3G Networks in the USA

We advise that all major mobile carriers across the USA will shut down their 3G networks to pave the way for their final transition to 4G LTE and 5G technologies. This change means that older smartphones and other devices which utilize 3G technology will no longer work while roaming in the USA. The phase out will occur as per the following schedule:

NetworkTermination Date
AT & TFebruary 22, 2022
T-MobileJuly 1, 2022
VerizonDecember 1, 2022

On the respective dates, all 3G devices will no longer work on those networks in the USA, and only customers using 4G LTE or 5G devices will be able to utilize roaming services.

As an interim measure, you will still be able to utilize your 3G, 4G LTE or 5G devices to access both mobile data and voice roaming services on the T-Mobile network until July 1, 2022. We have already made the necessary adjustments to automatically register your mobile devices on the T-Mobile network upon your arrival in the United States. There may however, be some instances where you will need to make the switch to the T-Mobile network manually as follows:

  2. Tap on “Connections”
  3. Tap on “Mobile Networks”
  4. Tap on “Network Operators”
  5. Tap on “Select Automatically”

  7. A list of available networks will appear
  8. Select “T-Mobile”

It is important to note, that while you will be able to utilize roaming data services and Wi-Fi on 4G LTE or 5G devices in the USA, you will not be able to make traditional voice calls while roaming until the VoLTE (Voice Over LTE) capability is enabled on our network. You will however, still be able to use mobile apps, e.g. WhatsApp, to make calls on these networks.


We are in the process of improving our network to implement the VoLTE feature in order to facilitate traditional voice calling while in the USA and will update this advisory as soon as it is available.


In light of these changes, and to ensure that you are able to stay connected while travelling in the USA after the shutdown of these 3G networks, we recommend the following steps:

  • Upgrade your device from 3G to a 4G LTE or 5G one that supports VoLTE
  • Upgrade your SIM card to an LTE SIM
  • Ensure that you subscribe to a suitable roaming package before departing
  • When the VoLTE functionality is available on our network:
    - Ensure that the VoLTE feature in your device is activated and updated with the latest version
    - Ensure that VoLTE is switched on prior to travelling
