Hi. Do the following to try and isolate the cause of the issue
- Restart your Verssed device
- Try a different SIM (or carriers)
- If you bought it second hand, then it IMEI may have been blacklisted after being reported lost or stolen
- If none of the SIMs works and you bought it new, then you will need to take it back you your retailer (if it is under 12 months old) or your nearest phone repairs shop as the antenna may have failed electronically.
