I have had no luck getting my Vibrant to work with my T-mobile blackberry plan. Phone works, but no data.
If I get a Captivate, unlock it, will it work with T-mobile's blackberry plan for data?
I don't care if it's just 2g and not 3g, I just want data...
I was told by AT&T that it wouldn't work because the data is provisioned differently. I wanted to keep my Bold 9000 for work and the Captivate for all other times and couldn't do it. I'll have to assume that T-Mobile also provisions their data differently.
At&t 3G runs off a completely different radio frequency so an at&t phone wont work on T-Mobile 3g. It will work with 2g and data provisions have nothing to do with it. Still a GSM network. Just get your unlock code for your sim and switch away

An unlocked Captivate will work on Tmobile but you will only get Edge for data.
There is a big draw back as these phone were never design with anythin less than 3G in mind. When ever I was using data (edge) all my voice call went straith to voice mail with no indications of any missed calls.
With Wifi it's fine. Even peoples with AT&T 3G have these problems when they travel to an area with only 2G coverage. Even a person in India told me the same thing with his Galaxy S.
Yeah with edge you cannot talk and use data at the same time. That's why when you're using data it will not allow calls to go through until the data stops transferring.

For some reason my Sensation 4G(TMO-US) won't data roam on AT&T network. Any ideas?
Here's the current situation... 2g is all I can get at home. My 2g icon is showing but NOTHING that requires data will work. I'm roaming on AT&T because I'm outside the city, and voice and text work just fine but when I check my data roaming via *#*#4636#*#* it says not roaming. YES I HAVE DATA ROAMING ENABLED. My gf has the Exhibit 4g and has no issues... When I put her SIM into my phone data works just fine. I've called T-mobile and they claim our phone settings are identical and data roaming is enabled on their end for my SIM but when i put my SIM into her phone it won't connect to 2g. I've removed the battery and SIM, toggled ciphering, had then rebroadcast my number and still nothing. AND YES it's a new SIM card, actually the 2nd one and Tmobile 4g and 2g work just fine as well when I'm in their service area. Any help would be appreciated since T-mobile doesn't see this as a big enough problem. Can I somehow enter an APN for ATT? I'm really out of ideas.

I have the same issue did you ever find a solution?
Tmobile had to have a tech rebuild my profile for their network. Took about a week or so. Everything has been fine since.

Hellos,
Was wondering and wanted to know from others, their experiences with using a D2G with different carriers/services.
I have a D2G on simple mobile currently. Switched from Sprint using an EVO 4G, data in my calling areas just stunk and never got better, forget ever getting a 4G signal..
But, it seems I am in an area between towers, because I seem to get the same result using Simple Mobile connected to Tmobile Towers. Signal drops from nothing to 3 bars if I turn around. And I only get an Edge data connection (I understand it's a frequency issue).
I was told by a Walmart Rep, that they use Family Mobile powered by Tmobile and don't have the throttle issue as with Simple Mobile, but 250mb data cap at the same $45/month as Straight Talk (even thought I'd be stuck at Edge with the D2G anyways) is too low a cap, especially if I were to switch phones later on.
So I recently read into Straight Talk as an option, after reading how bad H2O data is and that Simple Mobile's 3G is throttled to 119kbs (tested on a SK4G, yeap confirmed 119kbs max).
So I wanted to know from others, what kind of data rates they are getting on various providers using a D2G.

I would not know about Droid using 2G (on my old phones what I used as T-Mobile EDGE) or what I call "100K data" connection since I don't get it around here. I am sure that my data connection at times has degraded to 2G, but I have not noticed that as being the issue, so I have not been able to perform a speed test while in 2G mode.
Last June 2011 I used a Droid style phone on Virgin Mobile USA prepaid. That was the Motorola Triumph. I can't recall as a MVNO who was providing Virgin Mobile's signal, but I think it was Sprint by that point (Sprint bought Virgin Mobile USA prepaid). In any event, I was not pleased with the VM speeds (that is, if I was not using WiFi). My speeds were consistently about 300K to 700K.
Currently I use Straight Talk and I am VERY VERY pleased with the service. When I bought a phone and a Straight Talk SIM card I opted for GSM AT&T service since it had better GSM phones than T-Mobile did.
Since Straight Talk is an MVNO (buying its signal or "tower space" from other carriers and spectrum resellers) one's Straight Talk signal and data connection will only be as good as the provider you chose to use with your Straight Talk account. I assume the same principle applies to CDMA and Droid (Motorola) handsets.
Where I live in San Francisco I get a better signal from GSM-based AT&T than I did with T-Mobile GSM handsets, so on Straight Talk's SIM purchasing site I chose to buy an AT&T GSM SIM.
Whereas with T-Mobile 4G I would often get 2G in most parts of my residence, with AT&T 4G (again, this is with Straight Talk) using an Samsung Galaxy S II and ATT HTC Inspire, I consistently get a strong 4G signal (says "H+" on notification bar). And speed tests have been outstanding, (using speed test net 2286 kbps download, 1130kbps upload). Those speeds are in the "slower part of the house). This does not matter most of the time, however, since I use WiFi 90% of the time.
Bottom line: I suspect one's physical locale, handset model, and provider (CDMA, GSM, or specific carrier) all play an important part in the speed and quality of a data connection. In other words, everyone's experience may differ, even with someone who has the exact same setup as I, but who lives down the block.
Is this even possible. To make the phone work on cdma and hspa. or gsm what ever you call it
Yeah if you use a gsm sim card just download phone info app from play store and change the radio to GSM. only voice and text works with this easy method. read the entire thread below to make data work. HSPA+ works on at&t but only edge for t-mobile. most worldwide networks should work with 3G or HSPA but you have to enter in the right APN.

I got it to work on sprint, but call and text only. No data, I couldn't get it to work.

i had a samsung s3 a while back and i was able to be on a call and surf the web with out being on wifi is this still possible?
This is a carrier specific thing. And yes you can do it if you have LTE or HSPA+. That is assuming you have AT&T as i do.
I'm on sprint... and all data gets knocked out once a phone call has been started or recieved LTE or not
on sprint with my S3 it worked even on 3g using data and phone on the s4 it only worked while on LTE/4g
I can confirm for both T-Mobile and AT&T that data and phone calls work together just fine.
sprint triband does not allow voice / data at the same time.

so its a carrier issue then...
Just wondering if this happens to anyone else. My N5 was originally on Sprint but just recently switched to TMO. I have noticed that when on the TMO network my phone will drop to 3G whenever I make or receive a call. As soon as the call is over it switches back to LTE.
If I put my Sprint SIM back in and use their network it seems to hold LTE while on the call.
This is not scientific and am basing this observation from the network signal indicator on the top status bar. And as far as I can tell it isn't affecting performance. More of a curiosity at this point.

this is how its supposed to work. phone calls cant go through the lte signal(in this case, with tmibile) to the phone, so it drops to 3G(H).
LTE in it's current implementation is a DATA ONLY service so when you make voice calls it drops that connection and connects the call. Since 3G is Voice/Data it shows the 3G/H connection available to you at that time. When you hang up it goes back to LTE.
With Sprint it uses CDMA so theres no simultaneous option with that so LTE is kept alive in order to deliver data at the sametime.
All expected behavior as already mentioned
Thanks for the info. Makes perfect sense how that is explained. I am rooted and cleaned out some apps I don't want. I'm particularly careful to not mess things up and noticed the change in behavior on TMO. Wanted to make sure something I hacked for Sprint didn't FUBAR the connection.

I noticed this too on ATT.
When in calls it drops to H .
Thanks for the explanation

It is called CSFB (circuit switched fallback), which will soon be replaced by VoLTE (Voice over LTE), which will be a plain and simple SIP-controlled VOIP call using LTE as carrier. Not sure if current phones can and/or will be upgraded to be able to do VoLTE, or if todays LTE handsets are stuck falling back forever...
