Try a soft reset. Even I have Airtel, but no such problem

Hi,
I also have similar problem with Lumia 525 after updating it to windows phone 8.1.

I am using Vodafone Postpaid SIM card.

I tried below things to resolve this, but nothing help as this is a software bug.

1) change Sim card twice.
2)done soft reset
3)Format entire firmware with Nokia software Recovery tool


But problem still persists, can anyone tell me how we can tell this issue to windows phone development team

I am not sure but issue might be due to Vodafone or Airtel itself. Sometimes my network goes, but after sometime it comes back too. I tried changing phone, the problem was still there, so no need to worry, it might be network issues, if you have major issues go to respective galleries & they will sort it out. I have noticed that network goes only during very heavy rains.

It's a network issue. Why blame WP for every little thing??
Things like this are out of the hands of MS....

Hey,

It's a bug in the phone.

When I change -----Settings-----mobile +SIM-------SIM settings---------Highest connection speed from 3G to 2G, this issue is resolved.

This is a temporarily fix settings Windows need to fix this bug.

When your phone is in 3g(i.e highest connection 3g), you're phone is in dual mode 2g as well as 3g. In all areas 3g is not available, so it goes off for some seconds & 2g is available. If you use 3g, only then keep your connection to 3g, otherwise keep it on 2g(because in dual mode your phone drains more battery)

same stupid problem was on 920. on 3G, the signal was fluctuating like hell! I suggest flash your phone with a different firmware, and after flashing set as new.

[Ritesh Bhatia]

Changing mobile+sim setting from 3g to 2g connections fixed the issue for now.

the same problem was on many 920 users back on wp 8.0. No one at MS or Nokia seemed to care for it and fix it.
