data service in shanghai/hk - Verizon Samsung Galaxy S III

has anyone been able to get data service via their verizon sim in shanghai or hk? no problem with voice coverage, but i've had data coverage in shanghai maybe 5% of the time. i couldn't deal with no data in hk and picked up a pccw sim, which works great. their HSPA+ network is pretty solid.
interestingly i've had the same issue with a 3 HK prepaid sim. totally fine voice coverage, no data (on their UMTS network). no convolution of APN settings has done the trick.
i'm on mf1 & liquidsmooth 2.9.

[Q] No Data Roaming

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.

[Q] Data Rates, signal, quality of service

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.

[Q] International Roaming and Still Using VWZ 4G LTE

...............just like the title says........is it possible?
I live in a border town with between USA/Mexico. I have the Mexico ad on so I get 1000 mins to use as if I where in the USA, but while being south of the border.
I noticed today, WHILE IN MEXICO. that I received a couple of emails by the notification sounds....it surprised me because I have selected "Deny Data Roaming Access" in the Global Data Roaming access menu. STILL I get the 4G LTE icon and therefore my device has data, BUT my voice service is ROAMING.
Is this possible?
Can I be int'l roaming voice and still be on VZW 4G LTE at the same time???
I even went and turned airplane mode so that when it connected again, it would ask me if I wanted to deny roaming data, I doubled checked to select "deny" and still my phone would be using data with the phone roaming, but with the 4G LTE icon and data access at the same time....
There is NO 4G LTE south of the border (there is but with a different carrier and different freq.), so there is no way it could have connected to int'l LTE, and on top of that by me "denying" access to roaming data.
I know voice and data are split in 2, that the sim carries the LTE duty, and CDMA does the voice duty, SO, it is in plain paper possible since the LTE signal is strong enough to reach, but the CDMA isnt, so it roams........
Also, if its really the case, wont VWZ rape me a new one by charging me int'l data since I actually was roaming according to the CDMA signal.
Anyone care to enlighten me???
Thanks.

Texting while in Jamaica:

Me and my family will be traveling to Jamaica this weekend. From looking at Sprint's coverage map, didn't see any coverage for Jamaica. Question, w/out enabling International services for our phones, is there an app we can use for texting each other? Would this only work if we are connected to a wifi network?
Update: Talked to Sprint, we have Sprint Global Roaming (not warming) which is free. We'll have unlimited text/data, but we'll get charged for any voice calls, $0.20/minute. We will have to connect to a GSM network when we get there.

Do they have to activate something on your phone to connect to a GSM network? My father in law is thinking about switching to our family plan but goes overseas to the Philippines a couple times a year and is worried about connectivity while over there which is all GSM. Thanks!
They updated our Profiles, not sure what got changed.......................then when we arrive in Jamaica, we'll have to go into Settings, More Networks, Roaming, Roaming Network, Automatic, Roaming Settings, check International Voice and International Data..........then Settings, Connections, More Networks, Mobile Networks, Network Mode, Select GSM/UMTS, then select one of the three networks that will be available.
