can any confirm whether GSM & CDMA sims will work on this ?
Wat is sprint bandwidth in mhz? will 800/850 cdma Mhz work on the specified nexus 5 cdma bands ?

Hi,
I purchased my Motorola XT720 in Sinagpore. It comes without SIM lock and it runs on 1700/2100.
But I currently use the phone with AT&T Wireless which uses 850/1900 WCDMA frequency bands. So I don't have 3G connection speeds.
Is there any way to switch the phone to use the AT&T frequency bands?
Thanks,
Greg

if your location doesn't use the same radio frequencies that AT&T does you'll never connect to anything but edge
Check settings>wireless networks > mobile networks > network mode. Try different options...goodluck
I recommend you to go here and check that your carrier has the same frequency bands that AT&T.

yes.. the net frequency of my carrier is :GSM 900/1800, W-CDMA 2100
and its vodafone qatar
That WCDMA band refers to 3G (or 4G / H+ as AT&T calls it). The Inspire uses 850 or 1900 MHz frequencies for 3G. It uses the 850/900/1800/1900 MHz frequencies for 2G or EDGE (GSM) which is why you're seeing EDGE connections with the phone. T-Mobile is the major US carrier using the 2100 MHz frequency for 3G. The Inspire simply isn't capable.

Hi
I was told this would be a better forum for this question.
I have a huawei ideos (older non X6 version) and supposedly it is unlocked. It works with 2g/edge. It does not work with t-mobile 3g. I have looked for APN information and the info downloaded to the phone when I connected to t-mobile network is identical to what is listed on the net.
ie. I added
MMSC: http<colon><twoslash>mms.msg.eng.t-mobile.com/mms/wapenc
xxx added because I can not post urls.
Things which are odd. When choosing access network, it does not say T-mobile 3G. It only says T-mobile 2g, Att 2g and Att 3g. According to the net this phone supports the frequencies for tmobile.
gsm link for u8150 not allowed.
shows HSDPA 900 / 2100 / AWS
HSDPA 850 / 1900 / 2100 / 1700
And the wikipedia entry for tmobile
shows
1700 MHz/2100 MHz UMTS (W-CDMA)/HSPA 4G (formerly 3G[31]) 2006 2008 (3G), 2010 (Marketed as 4G) First carrier in the U.S. to deploy services on AWS frequencies. Markets HSPA+ as "4G". UMTS band IV
Not sure if HSPDA spec is same as HSPA though.
I did the trick where you enter #*#*4636*#*#* and checked phone settings. I changed the setting from CDMA to GSM auto (PRL). I also tried to hit menu and select radio band, but it pulls up an empty "Set GSM/UMTS Band" dialog. There is nothing to select.
I guess my question is, does this phone support 3G for t-mobile and if so, what setting am I missing?
thanks in advance.

I got an email from Huawei support
Hi,
Just as another data point. I got an email regarding this issue from Huawei support. They said an unlocked phone from one provider may not fully support 3g on T-Mobile. I asked them what he meant by not fully support.
Here is an excerpt from the Huawei email:
This phone is capable to be used in 3G that is correct, however if the phone is unlocked from the original provider it may not be fully compatible on 3G on the different providers network.

Moving to Q&A
three more datapoints
Hi
I got another note from Huawei. They said they don't support unlocked phones.
I talked to t-mobile support. They said the u8150 uses PPP and not RMNET. I have never heard of RMNET, and that the phone would only support 3G if it was rooted.
This seem like BS all around to me. T-mobile and Huawei.
I did test my phone with a friends tmobile sim and the phone behaved the same. ie. edge only.
Some more datapoints
Hi
This phone is available in two different frequency capabilities. Considering mine can see the ATT 3G network, it must be using the second set of frequencies. This second set is listed as usable by T-Mobile as well. Here is the info:
From the huawei spec sheet.
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 and it is also in the second set)
This second set of frequencies is also used by T-Mobile so I don't understand why this phone can not connect to T-Mobile 3G using my simcard or my pals.
It's all about the supported 3/4g bands. Most carrier Androids only support their networks spectrum's. Check gsmarena to ensure compatibility.
Hi,
Thanks for the info. Maybe I don't understand, but I thought gsmarena showed this phone as using both the Att and Tmobile bands. I remember when I had nexus ones was that one version was for ATT 3G and one was for TMobile 3G. I'm guessing that the 8150 is similar with the exception that huawei has not published accurate docs. ie. their docs say both frequences for all phones when in reality its two different model phones with only one label.

I apologize for not reading all of your posts
This isn't BS. It's the same issue facing Cricket phones attempting to connect on Verizon. I'm not fully up to speed but it looks like RMNET needs to be added via the kernel (edit sources and compile).
The below thread isn't specific to Tmo but it should give you some insight.
[04JAN][TMOUS]CMYLXGO's Stripped & Squashed Stock Desire HD[KERNEL:gauner1986][RMNET]
This is what Huawei meant by "may not be supported". However, if the phone connected to Tmo with SIM then it's already carrier unlocked. You now face the above issue plus prl, etc.
You face a long road ahead. My suggestion, sell the Huawei and buy a used Tmo Android.
How can this phone G2 D801, support LTE band IV and 17 without those frequencies, of 700Mhz and 1700Mhz?
It it only a HSPA+ (4G) phone?
The specs list frequencies for GSM / WCDMA and bands for LTE. D801 has bands 2, 4 and 17, so 1900, 1700/2100 and 700MHz. When scanning for networks I see AT&T, T-Mobile, former Metro PCS, and Verizon LTE networks.
hi
its unlock or lock?
I have lte
Sent from my LG-D801 using XDA Premium 4 mobile app
This g2 is capable of LTE, although it is going to use allot of battery.
i just purchased HTC 6525lvw (Verizon) and came to know that it only supports band 4 and 13 not the band 3 that is 1800 mhz which is used in most of Asia, athough my gsm network is working perfectly but i purchased the phone to use LTE services. Is there anyway out?
Sorry but no, there's nothing you can do to fix that.
