Before I had the 3G sim that the reps put in upon purchase of my phone. Went back to get the 4G sim & noticed a change under the network settings. With the 3G sim in, it would mostly display HSDPA but since the 4G inserted, it now displays UMTS most of the time.
Don't know the difference. When I look up UMTS it says its the HSPA+/HSDPA/HSUPA family of frequencies.
