[Q] Using a GSM phone for a CDMA service? - General Questions and Answers

Before I begin, I'm not certain if I'm in the wrong forum but I'll know eventually..
Is it possible, (if so, how) to use a GSM phone for a CDMA service, Sprint to be exact.
all in all, can i use my tmobile galaxy s2 (unlocked) for my new sprint service?
if so, how can i go about doing that?!?!?!?!

Google helps...

i googled around a bit and found that Sprint uses the 1900 MHz band for both voice and data service.

Sprint USA uses MHz
800/1900 for 2g
1900 for 3g
2500 for 4g
Infact you will not be able to make calls if your region uses 800MHz for calls.

what are the t mobile sensation bands ?

what is the phone bands in 2g network and what in 3g network ?
thanks !!
I believe these are accurate.
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1700 / 2100
You will be able to get 3G on T-Mobile in the US and on European networks, but it will not work on other North American carriers like AT&T, Rogers, Telus, etc. On those networks, you will get standard GSM/EDGE (2G) service.
it has 2100 in 3g for sure ?

Yep. Check out the product specs from the HTC website. Scroll down to the bottom of the page to the section titled Network.

[Q] Regarding Radio

Hello All! first of all its extremely basic question.
I have UK version of HTC One S S4, but i live in Indiana, US. I use Tmobile but dont get 4G or 3G..just Edge!

OK sorry but my Phone is not UK..it is HTC Europe version.

Your in a bit of a bind then since you have the international version! Your phone might not have the right frequency support to get T-mobile 3g/4g until they complete their move of 3g to the 1900 band.
This is an excerpt from Anandtech Review
The International and T-Mobile One S differ in what UMTS bands are supported, as the International One S targets both Asia and Europe, while the T-Mobile version goes for the Americas. I’ve made a table with the pertinent information.
HTC One S - Network Support
GSM/EDGE Support 850 / 900 / 1800 / 1900 MHz
WCDMA Support
One S - International 850 / 900 / 2100 MHz
WCDMA Support
One S - T-Mobile 850 / 1700 / 1900 / 2100 MHz

You really need that 1700/1900 band for AWS 3g. However, t-mobile is currently moving 3g to the 1900 spectrum which should enable you to get 3g when it's done in your area.
Here is a map of current reported 1900 3g coverage. http://www.airportal.de/
Sorry to give you the bad news.

that thread didn't help. The frequencies are the same... still it won't work
If it works with Rogers/Fido/Koodo, it probably won't work with Mobilicity.
Could the i9023 UMTS spec in gsmarena be wrong? Or are there 2 variants for i9023?

Are you sure you have the i9023? If gsmarena specs were indeed correct, it should not have worked with Koodo 3G.
Check the IMEI label under the battery for the model number.

Keen eye. Because Koodo only has UMTS 1900
HSDPA 850 / 1900 / 2100 - i9020A for AT&T
HSDPA 900 / 1700 / 2100 - i9020T for T-Mobile
So what you would need for mobilicity is a i9020T... They're different hardware, not just a flash away.

Your i9020a supports worldwide 2G bands, and 3G bands for Rogers/Bell/Telus/Koodo (850/1900) as well as most Asian/European (2100) carriers.
If you want 3G 1700 (Wind/Mobilicity) support, trade for an i9020t.

iPhones would be similar to the i9020a. Works with big 3 and most Asian/European (3G 2100) carriers, including India's.
In fact, almost all 3G phones have 3G 2100 support. Buy any 3G phone in North America, unlock and usable in India.

As Nexus phones came SIM (carrier) unlocked, you can use it in India (2G or 3G).

kk, thanks, so only companies that support UMTS 2100 will work with the nexus phone, correct?
thanks once again!

If you are talking about Indian carrier, yes. For worldwide list of companies and their supported frequency, refer to
http://en.wikipedia.org/wiki/List_of_UMTS_networks
http://en.wikipedia.org/wiki/Mobile_Network_Code.
Your i9020a would have UMTS 850, 1900 and 2100 support.

Support for 900 & 2100 mhz (3g) ?

Does the relay 4G use the 900 and the 2100 mhz bands ?
Some sites day it does, other say it doesn't.

if you're asking if it works for hspa outside of US yes, it does. apparently wcdma is 2100mhz everywhere but in the US
I'm just wondering if 900 Mhz does also work (the phone has it?)

F350S uncompatible in UK

So i just bought a LG G PRO 2 checked it everything seemed to work fine
But then i realized the network connection drops every few mins and reconnects only to a G signal (2G)
so upon further investigation i discover that the band frequency on this model is CDMA eg. USA + Canada
To say im P*&^ed off is an understatement clearly the person who sold me this is aware and is now ignoring any contact i try to make with him
I have contacted LG to see if i can possible purchase a motherboard for model D837 or D838 as i see this is my only option to get the device working
Unless anyone here can advise otherwise
Once i go into the band selection screen and disable CDMA bands it seems to sustain a stable connection but only to a 2G network haven't been into a 4G area as of yet to test but it is completely incapable of connection to a 3G frequency within the uk which i will be connected to 80% of the time
not 100% with the F350 but the frequencies for it should be:
2G: GSM 850 / 900 / 1800 / 1900 MHz
3G: UMTS 2100 MHz
4G: LTE 850 / 1800 MHz
2G is fine, as UK uses 900/1800.
3G: all UK networks at 2100.
4G: only EE/3 use the 1800MHz frequency. no-one uses 850 in UK.
look around the forum for the secret menu and see if you need to enable 3G/4G manually. or do a manual firmware update.
,My Wife has an F320S (G2)and she can enable all Bands in the Hidden Menu and works fine in Europe in Austria.Network Operator is Three (HG3).
I think the F350S is the same.
Go to Dialer and tipe 5457#*350#
in Modem Settings can you aktivate all Bands what you need
I hope this works for you.
Thanks for the reply guys
There's loads of settings in the hidden menu
I cant see how changing anything in here will help as it is a CDMA device which means it physically does not have the necessary hardware to connect to a 3G network in the UK
As it uses a totally different technology than UMTS
Ive discovered at WCDMA is actually UMTS so i cant see why it doesn't work ?

Those are the default settings that the device is on so no joy with that thanks anyway
using my EE sim signal drops frequently using my daughters O2 sim it seems to sustain a connection but again only to 2G network
Clearly the problem is the WCDMA bands on the device are 850 / 1900 / 2100 while 2100 is used here 900 is the more widely available and thus incompatible with device
I think my only option is to sell it on but to who its no use to anyone in the UK really
