If your smartphone supports Dual SIM (Physical SIM + eSIM or Dual eSIM), you can use Solis Zero alongside your existing mobile service.

This allows you to:

• Keep your primary phone number active.
• Continue receiving calls and text messages.
• Use Solis Zero for mobile data while traveling.
• Avoid expensive international roaming charges from your home carrier.

Can I Still Receive Calls and Text Messages?

Yes.

When Solis Zero is selected as your mobile data line, your primary SIM can remain active for voice calls and SMS, provided your device supports Dual SIM functionality.

Please note that your home carrier may still charge international roaming fees for voice calls or text messages received while abroad. We recommend checking your carrier's international roaming policy before you travel.

Tips to Avoid International Roaming Charges

To help prevent unexpected charges from your home carrier:

• Set Solis Zero as your mobile data line.
• Turn Mobile Data off for your primary SIM.
• Disable Data Roaming on your primary SIM.
• Keep your primary SIM active only if you need to receive calls or text messages.
