For all of sudden i am seeing SIM Error on both my new lumia 730 and 630, also the old 530 dual sim gets automatically into sim error, and since its all of sudden i am sitting unaware of being disconnected, do other also face such problems, is there a work around for the same. ??

Looks more like a provider (SIM) problem then a problem with your phones.

If you haven't gotten any reply, than it could be that you suffer from the same issue like me and my Lumia.
I understood that it is not just us...

The SIM socket gets worn out and the contact is not strong enough.

What have I done?

I taped the SIM on its back, to make it thicker and it did the work.

I also added some tape on the back of the SIM drawer.

Good luck!


BTW, you still had warranty the device should have been replaced.

I have a sim connection error today also. All three sim cards would not lose contact simultaneously.
