Nokia Lumia 521 3G not working

Hi,

 

I have a carrier unlocked Lumia 521 which I am trying to use in Asia. I am unable to connect to my carrier's 3G network even though network's carrier frequency is 2100.

 

What could be the problem ?

 

Thanks,

Rishabh

Are you using your carriers sim or a local sim?

RM-917 = Nokia 521 = AWS. Your Nokia works on the 2100 band, but only in AWS mode which is a US specific band using 1700 and 2100. or said differently: Your observed behaviour is normal.

Thanks for the info.

 

So you mean to say that 2100 band in US is different from 2100 band in Asia/Europe ? Since the phone says support for HSDPA 2100 I assumed it would work on 2100 network anywhere in the world.

 

Interestingly, I have a Lumia 520 also which works perfectly fine on 3G network in Asia. So, if both 520 and 521 are based on the same hardware, why shouldn't 521 work on 2100 network outside US.

Because the 520 is a global variant while it seems the 521 is exclusive to T-Mobile US only

gurish, although AWS uses the 2100 band it does in a complete different way, compared to a normal 3G handset with 2100 support. AWS is AWS, and the Nokia 521 is AWS.

I have the same problem. I unlock my T-Mobile 521 and brought it to Costa Rica and it doesn't work. Now I am going to Korea and need to know how to make it work there. I appreciate any replies.

Not possible. The required hardware is not present.
