I have Technno Phantom Tab its calling tab that supports calling feature. I liked this tab for affordable price and calling feature so I purchased it right away, but the problem is suddenly it stopped detecting my Sim card in it. So I tried inserting other Sim cards too but still not detecting?
Why my calling tab is not detecting any Sim cards?
Try answering the following questions
Have you recently applied any updates to your mobile?
Did anyone drop your tab accidentally?
If the answer for the any one of the above questions is yes, then I believe you need to take the Tab to the support center. With this particular problem there is very little one can do on their own.
Only remaining solution is opting for a factory reset. Make sure you take full back up of your data/contacts before you rest your phone.
