So I travel here and there and usually have no problems with my phone wherever I go, with the the exception of Turkey, Turkey has always given me problems. Whenever I go there I essentially have to buy a disposable mobile. This is because they block your phone with the IMEI number from their networks. To avoid hassle and/or cost I decided I would buy a cheap Turkish mobile phone there for use there exclusively. After a while of travelling there and back (and very limited use) its microphone became very weak to the point where I have to shout for the person on the other side to hear me. So I bought another different mobile, again same problem developed after a while. At this point I'm thinking that it would have been easier just to look in to somehow registering my own phone. Has anybody registered a mobile phone in Turkey? Is the process straightforward? Is there any downside to doing so?
