Thinking About Buying a 9930 from Sprint or Verizon and Unlocking it over to AT&T
- Has anyone tried to buy a Sprint/Verizon 9930 and unlocked it to use with AT&T? Looking at the specs, the 3G frequency bands for are the same as AT&T 9900:
Sprint/Verizon 9930 Frequency Bands:
CDMA 850 / 1900
GSM 850 / 900 / 1800 / 1900
WCDMA 900 / 2100 (3G Frequency Bands)
AT&T 9990 Frequency Bands:
GSM 850 / 900 / 1800 / 1900
WCDMA 850 / 1900 / 2100 (3G Frequency Bands)
Just wanna see if anyone else has tried this before I shell out $50009-12-11 07:53 AMLike 0 -
You want a GSM phone, wait on the GSM 9930 to drop or get a 9860.Last edited by ColdSunshine; 09-12-11 at 09:27 AM. Reason: Fixing my own bad typo

Other unlocked Blackberry devices such as the Verizon / Sprint CDMA Blackberry 9930 will work if unlocked but with T-Mobile / At&t you will get 2G connection (EDGE).
The 9930 will work with 3G on some networks outside the USA but, with T-Mobile USA / At&t the Blackberry 9930 from Sprint / Verizon will work only on 2G (EDGE) - not fast as 3G but it can still work as unlocked device and everything.
I think that Rogers Blackberry's are also can be a good option and they can be found in the US and far as i know it can work on 3G with at&t.
If you get the Verizon 9930 - after unlocking it you can change the CDMA settings on the screen that you can get by dialing ##000000.
With Sprint devices this screen is locked with a password and you will need to do SPC/MSL Unlocking to get that password after you have unlocked your Blackberry for GSM by MEP unlocking code.Last edited by blackberry-unlocking710; 09-12-11 at 10:15 AM.

It's no different than importing a Nokia N8 with a Pentaband radio and getting 3G on any GSM carrier in the world.
The 3 frequencies in that phone are balanced for World Usage, but if you are fortunate to live in an area where AT&T is using the 2100 band, you will get 3g on that phone.
I cannot believe you're even trying to argue about this.
There are T-Mobile phones that have an "extra" band that get 3G in some AT&T coverage areas, as well...
Facts are your friends.09-12-11 07:15 PMLike 0 - AT&T doesn't have a licence for 2100mhz.
AT&T uses only 850 or 1900mhz for 3G/H+.
North American use of the 2100mhz band is part of the AWS 1700/2100mhz frequency band and is completely different than how Europe uses 2100mhz.
As a result, phones like the Tour, 9930, etc can only operate on 2g/Edge in North America when they are connected to a GSM network (AT&T, Tmobile, Rogers, etc..)
Those are the facts. The 9930 will never see 3G/H+ in North American use.09-12-11 10:22 PMLike 0 - AT&T doesn't have a licence for 2100mhz.

- i bought a bold 9930 from sprint. It was difficult to unlock because of the extra security they have. The normal unlock code (mep code) is not enough because it will only allow text messages and phone calls and no blackberry services such as internet and bbm. You also need a SPC / MSL which is more expensive than normal codes. After i entered this code it finally said att when i put my phone number (be careful because most sites only sell you the mep code, on ebay its easier and cheaper to find and itll say spc code.
My phone works but not as it should. I cant open mms messages and i can only use EDGE so its alot slower than using a normal att blackberry. I even called att and there is nothing they can do. Im thinking about selling it since i cant use it to its full capacity. Anyone know if theres a way to use the 3g on 9930 from sprint? is the 9900 any different or will it not work on that either?10-21-11 06:36 PMLike 0 - the blackberry bold 9930:
Dual-Band: 800/1900 MHz CDMA/EVDO Rev A networks
Quad-Band: 850 / 900 / 1800 / 1900 MHz GSM/GPRS/EDGE networks
Dual-Band: 2100 / 900 MHz UMTS/HSPA networks
HSDPA : 14.4 Mbps
HSUPA : 5.76 Mbps
The blackberry bold 9900:
UMTS: 2100/1900/850/800 MHz or 2100/1700/900 MHz
GSM/GPRS/EDGE: 850/900/1800/1900
HSDPA: 14.4 Mbps
HSUPA: 5.76 Mbps
I know att uses 850 and 1900mhz so the best bet is to buy the 9900 and hope it works, i havent gotten an answer if it will but i got the 9930 and it doesnt work 36 but then again the bands dont say 850 and 1900 like the 9900... i havent read anywhere that the 9900 wont work with att 3g... i know the 9930 doesnt.10-21-11 06:54 PMLike 0 -
