You can see the four WCDMA frequencies that our devices support (850, 900, 1900, 2100).
I need 850 Mhz in 3G mode, but this frequency comes deactivated (see the attachment) i can only activate 900 and 2100...
Thq¿e question is...Can i flash another ROM or baseband to make this work??
Can you talk with your russian friends for any advice?
The phone is working excellent in all their functions, i only need to "open" that 3G frequencies.
Any advices or help?
I used mobileuncle app, i do this screenshot attached (i do not have the posibility to activate the frequencies i need)
Thanks in advance for all.
Been following this thread as some good discussions but honestly confused here
I am located in USA and am on ATT network
According to an ATT message board, ATT supports the following
For GSM 850 MHz and 1900 MHz.
For HSPA+, 850 MHz (Band V) and 1900 MHz (Band II)
For LTE 700 MHz (Band XVII) and some 1700 MHz (Band IV)
Can i use this Coolpad 9976 on ATT..would I be limited to like one frequency only on both GSM and 3G? Thanks for any advice (was about to buy this but held off)
