why my lgv20 doesnot read sim card

[Android Central Question]

since they repaired its charging system i think the guy spoilt it some how then told me problem was with my software

 

[belodion]

What software exactly? What test of the SIM-reading hardware was done?

Can you provide details to the whole story? You said it got repaired? What repair was done? Try a factory reset and then try another SIM card and see if it reads. Also, what model and carrier do you have? There's a chance of physical damage, or the repair guy forgot to plug in all the wires inside therefore it's not reading.
