First, take the SIM out and insert it back in, making sure that it fits exactly in the slot. Then manually connect to the network by following the below steps:
A. Find an option called Lycamobile Services or Lyca Services on your phone. This will likely be found somewhere in your settings folder, under ‘Tools’, ‘SIM’ or among the apps.
B. After finding Lycamobile Services, select Lycamobile > Mode > Manual > National.
C. After selecting ‘National’ your phone will return to a previous page or start the Manual Network Search by itself.
D. Following this, reset your phone without taking the SIM out and then start the Manual Network Search again.
Once you have manually connected, restart your phone.
If after several attempts the above procedure is not working, check the SIM card’s surface for scratches or cracks. If the SIM is damaged, go to your nearest retail point for further assistance.
