What's the difference between the 8150-B and 8150-D?

I have a Ideos 8150-D, I was wondering what the difference is between this model and the 8150-B.

I think it's the CDMA frequencies it works on, but if someone could be more specific, that would be great.

Cheers

Rog :D

I believe the D is also sold as the tmobile comet, which means the '3g' frequencies the phone uses are 1700/2100 as opposed the 'B' which uses 900/2100.

I asked Huawei this question:
Content:Would you please explain what the differences are between the Ideos U8150B and the U8150D Smartphones.
Huawei's reply:
the same model customized by different service provider

According to the Specs, both U8150B & U8150D are identical and will operate in 2G (GSM 850/900/1800/1900)
3G (HSDPA 900/2100/AWS)
HSDPA 850/1900/2100/1700.
I am assuming from Huawei's reply that "B" phones are "locked" to the Network of the service provider as my "D" model was open to any Telco Provider I chose.
I'm awaiting further info from Huawei and will Post when it comes. Neil.

Hi John, the reply I got from Huawei said there was no difference between B & D IDEOS U8150 phones. What they tried to say was that the phone is "Service Provider" locked. ie, will only work with Vodaphone or TMobile or Verizon and need to be "unlocked" to work with any SP you choose.
My observations would suggest that "B" is the locked version and "D" is not.
To check whether your phone is "locked" follow this procedure:

Dial *#*#2846579#*#*
Select ProjectMenu
Select 5 Network Setting
Select 4 SIM card lock state query.

It will then display SIMLOCK DEACTIVE for unlocked
and NW LOCKED for Network Locked.

Naturally, if NW LOCKED is displayed - you may need to pay to get it unlocked.

I hope this is the answer you were seeking. Neil.;)

Thanks. The keysequence you mentioned does not work for me. After the last * it clears the dial pad entry dialog but does not go to a new screen. *#*#4636#*#* does work for me though.

I talked to tmobile last night via phone. I thought the guy was speaking bs, but he said this phone does not work on 3G because it uses PPP protocol. He said it needs to use rmnet. And the only way to get this to work is to use a modified rooted firmware.

Hi John, I would suggest you go to :HUAWEI IDEOS - Huawei Device Co., Ltd..

If you look under > Smartphones > IDEOS U8150 > Downloads > FAQ's in PDF.
I have Downloaded and printed out the User Manual and the FAQ's Manual and I find these lay out the process to use your phone and find out what it's doing.
On your phone if you go > Settings > Wireless & Networks > Mobile Networks > Data Enabled you will see that you have the ability to > Use only 2G Networks.
This suggests to me that 3G is already enabled. Cheers Neil.

Hello Neil,

That link shows the key bit of info.
HUAWEI IDEOS - Huawei Device Co., Ltd..

At the top it shows
UMTS 900/AWS/2100MHz or
UMTS 850/1700/1900/2100MHz;
EDGE/GSM/GPRS: 850/900/1800/1900MHz

According to Wikipedia

ATT
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
850 MHz UMTS/HSPA 3G
1900 MHz UMTS/HSPA 3G
700 MHz LTE 4G

T-Mobile
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
1700 MHz/2100 MHz UMTS (W-CDMA)/HSPA 4G (formerly 3G[31])

When I connect to wireless networks, I see three choices:
T-Mobile 2G
AT&T 2G
AT&T 3G

So I am guessing my u8150 is using the second UMTS set of frequencies:
1. 850 (since it sees two edge networks and that is only available in the second set.)
2. 850 and 1900 (since it see's AT&T 3G)

This second set of frequencies is also used by T-Mobile so I don't understand why it is not available.

Hi John, I'm still learning about this Technology myself. I firmly believe in following the Manual instructions, but there is an assumption that anyone who purchases a cell/smartphone these days - knows it all!
I Google a lot - and from what I can gather, your phone will use the bandwidth provided by your Provider at the nearest Cell Tower to you and your phone.
Once again, I am assuming that all the specs shown to be built into the phone work automatically unless we shut them down manually. ie. to save battery life etc.
Abbreviations such as HAC (Hearing Aid Compatibility) meant nothing to me till I Googled for the answer. Hope this helps.
We have in NZ Telecom/Vodaphone/2Degrees as our main providers, and the signal strength for 2Degrees (my provider) vary quite a bit due to Topography. Cheers Neil.
