Yes. All prepaid and postpaid services on 3G devices in the US will be impacted – voice, data and SMS.

Yes. If you have 4G LTE or 5G devices you will still be able to use your device to access data roaming services in the 4G LTE or 5G network coverage areas. This means that customers will still be able to use their mobile apps to make calls, send texts, check emails, browse and watch content.

In order to access traditional voice roaming on 4G LTE or 5G networks , you will need to have a VoLTE (Voice over LTE) capable 4G LTE or 5G device. This is the functionality that makes it possible for voice quality calls to be made over the LTE/4G mobile network. This feature will need to be activated on the device in order for you to be able to make these calls.

At this time, we are in the process of improving our network to implement the VoLTE capability to facilitate traditional voice calling while in the USA. We will update our website as soon as it is available.

Most recent 4G/LTE SIM cards will work with VoLTE. If you are unsure, visit our store. In case you do not have an LTE SIM card, we will swap your SIM card for free.

  • 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 VoLTE feature in your device is activated and updated with the latest version
    • Ensure that VoLTE is switched on prior to travelling
