How to Check If Your Phone Is Carrier-Unlocked

Before purchasing a SIMO ON or Solis Zero eSIM, make sure your phone is carrier-unlocked. A carrier-locked phone may only work with the carrier it was originally purchased from and may not support SIMO ON or Solis Zero.

For iPhone

1. Open Settings.
2. Tap General, then About.
3. Scroll down to Carrier Lock or Network Provider Lock.
4. Check the status:
   • No SIM restrictions: Your iPhone is carrier-unlocked and can use SIMs or eSIMs from other carriers, subject to device and network compatibility.
   • SIM locked or another restriction is displayed: Your iPhone may be carrier-locked. Contact your carrier to confirm your unlock eligibility and request an unlock if needed.

For Android

The steps may vary depending on your phone's manufacturer and model.

1. Open Settings.
2. Look for Connections, Network & Internet, or SIM manager.
3. Check whether your phone provides information about its network or SIM lock status.
4. If you can't find the information, contact the carrier your phone was originally purchased from and ask whether your phone is carrier-unlocked.

You can also try using a SIM or eSIM from another carrier. If it activates successfully and connects to the network, your phone is likely unlocked.

What If My Phone Is Carrier-Locked?

Contact your original carrier to check whether your phone is eligible to be unlocked. Once your carrier confirms the phone is unlocked, try setting up SIMO ON again.

Note: A carrier-unlocked phone must also be compatible with SIMO ON and support eSIM functionality. Being carrier-unlocked does not guarantee eSIM or network compatibility.
