Samsung Galaxy S2 (GT I9100), low reception of 3G compared to 2G

#1

I have purchased a Samsung Galaxy S2 from UK. It was a used one. Now when I want to use 3G, it gets a low signal. Like 1 bar or none at all. What can I do? 2G reception is impeccable though. I have flashed some modems on it. But none solved the issue.
Note that the sim card used in it is the same I use in my other phone and the other phone has an excellent 3G pick here.
Thanks much

There is no problem with IMEI. The imei is fine. I have used other sim cards in the phone. Same think. I asked the seller, he said he has been using the phone 3G working fine on it.
