Problems with SIM Card

[jbradz99]

Yesterday morning I woke up and found that my iPhone 6 was struggling to find a data connection. I live in an area with 4G signal yet the top left corner read ‘searching’ despite walking into town and trying it there. I’ve restarted the device and removed the SIM card yet none of these methods have worked, does anyone have a similar issue or has anyone found a solution? (This issue is also preventing me from sending text messages and calling people as it is acting as if I do not have signal).

You can try cleaning the SIM  a dry cloth and then you can try switching on the device again.

If it is still not working, then  it might be locked to another network where you have used it earlier. You'll need to get it unlocked by the mobile provider you originally bought it from.

if this also does not help, try buying the replacement sim.
