Keep your primary number for calls and texts

On a compatible dual-SIM phone, you can keep your regular number active for calls and SMS while using encryptSIM for mobile data. Your primary carrier must support service where you are traveling.

Calls and texts on your primary line remain subject to your carrier’s charges. Turning off data roaming does not prevent voice or SMS roaming charges. Check your carrier’s terms before traveling.

Before you travel

Menu names and dual-SIM behavior vary by model and software version. Keep data roaming off on your primary line unless you intend to use that carrier’s roaming data. Follow your encryptSIM plan’s instructions for roaming on the encryptSIM line.

Receiving calls, SMS, and verification codes depends on your primary carrier and network coverage. A call on one line can affect availability of the other line, depending on your phone and carrier.
