my signal shifts from G to H or 3G and then the signal loses strength.In G the signal strength is maximum.I tried other sim cards in the kaiser and it works perfectly.Also my sim card works perfectly with no signal loss in other cells.Also,I havent installed any new ROM.All the specifications are same as when i bought the kaiser

I purchased an unlocked I9305T a few days ago to use on Telstra and am having all sorts of reception problems even though we're fairly close to a tower. My S2 will usually get -80 dbm and above whereas the S3 was often sitting at -100 or less. Sometimes mobile data works and other times it drops out constantly or won't connect at all.
Anyway I was ready to return the phone today when I noticed that without a sim inserted, it's getting better 3G reception than the S2. That would rule out any antenna or modem problems wouldn't it? Does this mean the sim card slot might be faulty? I doubt it's the sim card itself as I've got it in the S2 currently and it's working fine.
EDIT: Please excuse the dumb stuff above. Don't know why I thought signal strength meant anything without a sim. I went and got a brand new sim and it's now working perfectly.
im on 4.1 and noticed it wasn't wanting to ring or text or connect to data on 2g but will on 3g
so I tried 4.3 didn't make a difference
what could be causing it not to work on 2g signal im using o2 uk I no spare sims to try another network
some strange reason if bars on 2g less then 3 it wont work could this be a issue with the antenna
Used my wifes Z1 to test my Z1 motherboard as I was having touch screen issues and a new screen didnt resolve it so wanted to test and see if it was a board issue which it was. Put wifes phone back together and now having signal issues.
Basically all signal reception strength seems to be reduced on all modes, data on 3G and HSPA+ is ok when signal strength is strong enough but on 4g I have very strange problems. On uk EE Although signal strength is reduced data transfer is still ok with 4g. On O2 however even with 4 bars i get zero data transfer. Have a Z3 tablet also on O2 that works perfectly on 4g. Tried swapping sims with the z3 still same result. Tried them both side by side tonight Z1 -95dbm 4g Z3 -89dbm on speed test z1 showed connection issues while Z3 showed download of 16Mbps. Have replaced aerial coax lead and aerial board without any change.
Apn settings all correct.
Any ideas what could be the issue?
Thanks

Greetings,
I recently replaced the charging port and swapped the battery after that my phone lost reception and only says no network, when i try to change the band from 4g lte to 2g or 3g nothing happenes..
Any solutions ?
I tried almost everything
Bought mi 11 in Ukraine few months ago with no data problems but now i am in Jordan and when SIM signal indicator is 2-3 bars 4g activates and works fine mostly but when signal indicator is full or 1 bar less there is no data or 3g activates which is super slow/not working
Any suggestions?
