Hi,

I bought a Nokia Lumia 820 3 weeks back. I live in India and BSNL is my carrier. I have gone through 3 different types microSIMs.

Initially my nokia dealer cut the old SIM which I used in my nokia expressmusic [5130/5310?]

This had terrible call clarity and lot of dropped calls.

Then I tried to get a new microSIM from BSNL, but they gave me a normal SIM with small contact points. And this SIM was cut to microSIM size. This did not help with the call quality and droppped calls.

Finally I got a real microSIM from BSNL. With this SIM i have not had many dropped calls. But I am not 100% satisfied with voice quality. Some calls are crystal clear but while others sound muffled. Almost like someone did a bass boost. I have not been able to narrow down whether it is a problem with my phone or the callers phone. But never had this problem with my old Nokia ExpressMusic

Any tips/suggestions appreciated.

thanks

I would test that sim you have in another phone if possible to see if the same happens,this will narrow down if its the phone or sim..

..and to answer the Subject line.."Can the type of microSIM affect call quality?" .. its not the TYPE but the condition e.g. old, worn out or improperly / badly cut (as in your case earlier) will SURELY affect the performance ...
