How do I get faster mobile network data using Sun Cellular mobile internet on my Lumia 630?

[WPCentral Question]

I bought a lumia 630 and im trying to use sun cellulars mobile internet and placed it as my default mobile data under sim 2. But when i turn mobile data on, status bar shows E and its so slow. Shouldnt it be H+ on d status bar? How can i make connection faster? Should i transfer it to sim1?

E means 2G. That could mean you don't have a strong 3G signal at your place.

re:

OK, try this:
1. Go to setings.
2. Go to cellular+SIM
3. Select SIM settings
4. For Highest network speed, select 3G.
If this works, then you're OK. Otherwise you can try another way to do that: The field test.
