[Q] International Roaming - Thunderbolt Q&A, Help & Troubleshooting

After CES, I'm beginning to put some serious thought into LTE and this phone. Dumping AT&T at this point is looking fairly good, as I've loathed their customer service for consistently soft-bricking my older phones due to their inability to properly unlock a phone.
How well does this phone handle roaming, especially in Japan, the UK and Australia? How compatible is the CDMA2000 EV-DO Rev. A. standard? I need to do a lot of travelling to these places and don't want to be short-changed. Does this support UMTS 2100 or international 4G? I plan to use the "buy a prepaid SIM" method.
Or should I be carrying around my unlocked Captivate for roaming?

If you want traveling to Western Europe (like in UK), forget it because GSM rules there. Just notice that the GSM represent 80% of mobile phone market but there is a website you can find the CDMA coverage in the world:
http://www.cdg.org/worldwide/
EDIT: About the 4G, a very very very few countries have it but it can be HSPA+ or WIMAX instead of LTE.
Another website for GSM coverage: http://www.worldtimezone.com/gsm.html

So, what you're saying is basically: Tote around the Captivate if I'm going to Europe, use the Thunderbolt for Japan?

In short answer, Yes
But you can't use the 4G Lte in Japon because it doesn't exist (yet).
Anyway, there is one carrier available which support the CDMA in Japan according to the website.

I do know that KDDI supports CDMA2000 and 1xEV-DO Rev. A on the right bands in Japan, so I'm hoping that it's enough. I don't need data roaming that badly, and if its service is comparable to Verizon's EV-DO service, it's good enough.

If youre gonna roam, bring along the captivate.
Or, you can get the droid 2 global, but there's no lte in there lol

Sir,
I want to buy Galaxy SII duos. It works with CDMA2000. However, I used to go to Hong Kong. I want to use 3G (i.e. WCDMA). Can I root the ROM so that it can works with WCDMA?

[Q] HTC Amaze on Wind or Telus?

Hi there,
Any suggestions on using Wind or Telus for HTC Amaze? I know that Wind/Mobilicity uses AWS (1700/2100) band, and that apparently doesn't penetrate buildings very well. And Telus uses the GMS, but don't like reputation. I would like to unlock the phone afterwards as I will be moving east during the year and if I am not satisfied with the provider well I would like to change.
Any tips on which company's phone would be easier to unlock and with which unlocking company you might recommend?
Thanks!
Wind unlocks after 3 months service. Telus doesn't. I think the choice is easy enough

1700/2100 Wind is using isn't all that different from any other carrier that much. Telus does not use GSM (in North America/Brazil GSM is 850 and 1900 mhz) Telus uses CDMA 800/1900 mhz. The lower the frequency the better penetration through the walls, but it goes into reverse as far as ability to carry data - the lower the frequency the less data it can carry. I've yet to grasp LTE and 700 mhz, seems so contradictory = high speed but voice only, who cares? Someone please fill us in...
Also, Telus uses the 850 band for HSPA. Therefore the HTC Amaze from both Telus and Wind could work on either network if unlocked.

Your information is quite wrong.
Telus had a GSM network since 2010, operating on 850/1900.
1700/2100 is a weird frequency for 3G service due it only "recently" getting use as a 3G band through t-mobile.
700MHz is a band that LTE can be used on. So are 1700 and 2100 (Rogers, Bell LTE).
tl;dr: buy a Wind Amaze. Try them for 3 months on some plan. It'll be cheaper than buying a Telus one and getting service for those 3 months, then paying to unlock.
I have to chime in here and say, every person ive talked to that is on wind sounds like crap, most of them complain about spotty service, i know the pub in the area i live in, which is a popular area you get 0 service inside or out, deal breaker for me. I like to sound clear and get service everywhere, and ill pay for it.
Go with wind. A lot easier to get out of in the 14 day grace period. Also a lot easier to get out of in general. Their networks are fine. Sorry to the above poster, but their networks are just fine. Sound quality is probably phone dependant.

No experience with Wind on the Amaze, but did have someone test it on their Telus connection and the speeds were very nice.
Works GREAT on the WIND network.
You can buy an Amaze from Telus without a plan, at least I did back in Nov. just had to drop an additional $100 on the total cost. I just unlocked it to use on Rogers network followed by Bell.
Decided to switch carriers, got the New contract and now the extra phone (Nexus). Good luck shopping the Amaze is a great phone!

An Amaze from wind costs 50 bucks less outright. Factor in taxes and stuff, and that's still your first month of service compared to buying a Telus one.
You also have to consider Wind is great when your in major centers but if your driving anywhere out of town, good bye service. Im in Canada dont know how big wind is in the states. Im not trying to hate on Wind, but in Calgary the service is pretty spotty, and were a pretty major city

Wind's roaming in the States is pretty inexpensive - $.25 for a minute. Most of Rogers users pay more just for being 100 kms from their home zone.
By the way Amaze is pentaband 3G phone - it will work with most operators in the world.

Telus and Bell are the best network choices in Canada if you travel often since they have shared network agreements. The only time I've ever roamed on the network was in northern Ontario which is still better than the 10 hours worth of no service driving on the Rogers network.

[Q] AT&T Galaxy S II i777 on T-Mobile

to put it plainly,
NO
the i777 does not support the required bands for accessing TMobile's 3g/4g network.
Had the merger gone through, possibly. But as of right now, no.
Tmobile is on 1700MHz and 2100MHZ while AT&T is on 850MHz and 1900MHz.
No, and this is the case for every AT&T device in existence to my knowledge.
In fact, the ONLY device I know of that is not sold by T-Mobile and supports their HSPA bands is the GSM Galaxy Nexus, which is one of the first (if not the first) phones to do pentaband HSPA.
Personnally I tested the Unlock Process with a T-Mobile SimCard...not sure if working properly due to a operation range described by the fellows

You can still get 2G on T-Mo because T-Mo uses the standard 850/1900 for 2G. What OP asks is 3G/4G.

How is that an exception to what I'm saying. The T-Mobile version is not a device sold by AT&T, and is, by definition, a device sold by T-Mobile.
It's always been a bit easier to get T-Mo phones to work on AT&T - a number of them support the AT&T bands. But it's never been easy (and with the possible exception of the Skyrocket, never even possible) to go the other way without losing 3G.

That would be the obvious answer based on the published specs, but I found an unselected listing in the hidden modem/ band settings for WCDMA 1700 MHz (Band IV) on my i777. I don't know if it works, but it's listed. From the phone keypad on the stock version, type in *#2263# and then look under Combinations. The phone lists 7 different GSM/PCS/WCDMA frequencies and only the obvious 5 are selected.
Anyone with an unlocked i777 on Tmo want to try it out?

Unlikely. Unless the phone has the hardware support for it.
I found out after extensive research on the Nexus One, that even though the radio chip inside it supports both frequency sets (pentaband, I suppose); the power amplifiers were only connected to certain frequency outputs, depending on the carrier it was advertised for. Which means even if I flashed a T-Mobile radio, the signal wouldn't be strong enough to get outside the case of the phone, let alone to a cell tower.
Your best bet is with European phones, as I believe they use the same frequencies as T-Mobile (since they're owned by a euro company).
Someone should confirm, but I would guess that the I9100 will work on T-Mobile with 3G.

No, WCMDA = UMTS = pure vanilla 3G.
2G = GSM/GPRS
"2.5G" = EDGE
3G = vanilla UMTS (WCDMA)
3.5G = HSDPA
3.75G = HSPA+
3.9G (it's not really 4G) = LTE
true 4G = LTE Advanced
Most phones, even if they support advanced modulation schemes (HSPA, HSPA+) will list the band support as "UMTSxxxx or WCDMAxxxx"
I heard (it's actually confirmed, can't find the article), T-Mo has the same 3G bands as AT&T in some remote part of the USA, I think somewhere in Washington state, not sure though? The OP might want to move there

That might explain why the Vibrant apparently supported one (but not both) of AT&T's bands.
As I understand it, unlike the N1, the international HSPA+ Galaxy Nexus is full-blown pentaband.
Tmo has roaming agreement with at&t. So it is possible in places there is no tmo tower, your tmo phone could roam to at&t tower without showing the roaming sign.

LTE is HPSA

I just got off the phone with Telus and they told me that LTE and HSPA are the same. So if I get the LTE version, unlock it, when i head to Europe in a few months the phone will work there too. (on other carriers)
Is this true?
Nope ,, its not the same
Thats what I thought, thx
HSPA+ should not be confused with LTE, which uses a new air interface based on OFDMA technology. HSPA+ is an evolution of HSPA that upgrades the existing 3G network and provides a cheap way for telecom operators to migrate towards 4G speeds without deploying a new radio interface.

Question about International Phone compatibility

I was thinking about buying the International unlocked Galaxy SIII GT I9300 and saw how it would be cheaper in the long run, but my main motivation was being able to move from carrier to carrier if I wanted to and not having a contract. I seem to be reading though that the international version is only compatible with AT&T and T-mobile at 3G and is not capable of 4G speeds at all. Also, that even American versions are not always compatible with eachother. So am I correct in thinking that if I get an international version I'll be stuck between T-Mobile and Sprint at 3Gs. And that nothing can be done to the phone to allow an International phone to work with Sprint or even an American Sprint to work on a T-Mobile network? I'm starting to think it might be easier to just get an American phone and jailbreak it.
The international one will never work with sprint or Verizon, the AT&T and t-mobile versions will never work with sprint or Verizon.
The difference is hardware, Verizon and sprint are cdma, the rest are gsm.
The international one will work with AT&T with 3g and 4g(actually its hspa+ which is technically 3.5g) and will work on T-Mobile only in 2g for now, in a few months it will work on 3g and 4g when they refarm their 1900 or 1700mhz (can't remember which) band to 3g.
No matter what you do to either the international or US gsm versions they will NEVER EVER WORK ON SPRINT OR VERIZON.

I see, that's what I was afraid of. The AT&T and T-Mobile option still seem attractive, but in your opinion will the Verizon/Sprint with a jailbreak route be better in the long term since the LTE is by far the superior option(from what I've read)? I've seen AT&T has LTE but the International version wouldn't be able to work on a LTE network anyway, would it??? I plan to download most things on my laptop and move them to the phone anyway, the only important thing to me internet speed would affect and my main concern would be live video chat, would the 3G or HSPA+ be sufficient for that? Other than talk and text the phone will be mainly used for games, movies, music and the superior GPU in the International version I think would be better for that? Are there any other phones comparative to the Galaxy III you know of that might have both the CDMA and the GSM, the "world phones" as I've seen them called?

You can't/don't jailbreak Android phones. Hard to even know what you are talking bout trying to accomplish? It's very simple.
1. Buy a phone from a carrier and use it on that carrier. That's the easiest option.
2. Buy an International GS3 and use it on AT&T 3G or 2G.
3. Buy an International GS3 and use it on T-Mobile 2G.
If you try any other options you are just going to confuse yourself.
Definitely don't get the sprint or Verizon ones, you are stuck on cdma then. The at&t one has LTE and the T-Mobile one has dc hspa+ (theoretically up to 42mbps) the international one has standard hspa+ (up to 21mbps) and I regularly get between 5-8mbps down and 2-3mbps up and I live in the country.
The gpu and cpu on the international one are better too.

I have a bad habit of using the words root and jailbreak interchangeably, I meant root the phone. I guess I have to decide how important LTE is to me. It'll either be AT&T or the International version. The superior GPU and CPU are attractive, but so are the LTE speeds. But I guess with the limited data maybe not. But thanks for your help, this clarified a lot for me.
Frequency Concern
I have the exact same problem!
I am planning to buy a Galaxy Nexus, which works for UMTS (850/900/1700/1900/2100MHz) and GSM (850/900/1800/1900MHz). I read from wikipedia that the 3G and 4G networks from Tmobile are carried on the frequency of both 1700MHz and 2100 MHz. Does that mean Galaxy Nexus can use 3G and 4G on Tmobile network?

Oh really?! Then I should sell my international version of Galaxy S II for a Galaxy Nexus. S II doesnt receive 1700MHz. I read from Wikipeida: This band (Tmobile 3G and 4G) was an area of wireless spectrum, half in the 1700 MHz (1.7 GHz) and half in the 2100 MHz (2.1 GHz) frequencies. SO I was thinking: Hey, how about getting a phone with both 1700 and 2100MHz to work on Tmobile 3G and 4G.
So you can actually use 3G? or even 4G on Tmobile? Is it so slow or weak that makes you want to change carrier?

Verizon Samsung Galaxy S4 to have AWS 4 Band (Tmobile LTE Capable?)

Hi,
So I've read the FCC documents located here: LINK
Page 1 and Page 5 are the most interesting! These state that the Verizon model SCH-i545 will have AWS band 4 (of course 13 too) which does support T-mobiles LTE network right? It never states 1700/1200 frequencies.
Thing I want to know from the pros is will this phone indeed offer LTE support for T-Mobile or and I'm just seeing things?
Also, for all the other people that are wondering if the ATT model will offer LTE support for T-Mobile as well? It will since it supports both bands 4 and 17 But wait is that AWS band 4?... the jury is out on that! -_-
Many Thanks

If I am correct, Verizon phones do not use sim cards (CDMA) and AT&T and T-Mobile are GMS (sim phones). So even if the bands are supported, I don't see how a Verizon phone would work on T-Mobile or AT&T unless they are CDMA / GSM dual phones. And even then they would have to be unlocked.

All of the major Verizon releases over the past year have come GSM unlocked. They are world phones that contain GSM and CDMA radios. I'm using a Verizon iPhone 5 on the Straight Talk (AT&T) network currently.
All lte phones have sim cards as it is a gsm technology. My girls verizon gs3 has a sim. As far as it being compatible that is a hell of a question.

Yes! I sold my iPhone 4s to get Samsung galaxy s4 and it sold to someone over in the UK world (Ireland) that says it works! Lol.
I've also seen threads about sim unlocking the Verizon S3 for domestic and international use. Some people use HiAPN as system app along with other steps and viola... Working on whatever network you want
Question is... Am I seeing right that Verizon S4 will support AWS Band 4 for t-mobile?

Hey this is one question i have lingering on my mind. How is the StraightTalk connection? Is it any good? Are there call drop issues? And do they have data plans?
if i buy a tmobile s4 will it work on verizon??
I know most things are under the catagory of speculation/rumor but i was wanting to to check out tmobile network for a bit.... the no contract is appealing. If i bought the phone outright and ending up not liking tmobile i would switch to verizon. Short of selling the tmobile and getting a verizon phone i was wondering about just activating the same phone on verizon?
Will there be "one phone" in US or would they all have thier own modem chips i guess is the real question....
thanks for the guesses and speculat'n!
You have to consider its Verizon and they have 700Mhz LTE and you can't roam on AT&T's 700Mhz so I would not expect to access Verizons AWS spectrum on T-Mobile or vice versa. Remember when they said LTE was the unifying spectrum to allow for easier use across networks and carriers, well that was a pile of BS.
Great news, but I heard verizon was purposely going to burn in their logo onto the amoled screens.

Wrong: those "700mhz" frequencies are different bands. Both T-Mobile and Verizon are building out LTE on the same band: 4 (AWS). They will be interoperable device-wise.
AT&T also owns a lot of AWS, and though they're currently running LTE on it only in one market (somewhere in Oklahoma IIRC), all their LTE devices do come with band 4 enabled.
The more I read about the differences, the more I'm convinced that the Verizon model is more cross compatible with all other services. It's still the only CDMA model. But it's also gsm unlocked if you know how to program APNs. Any thoughts?

I posted a pretty detailed analyzation of the LTE bands the different GS4 models work with here: http://forum.xda-developers.com/showthread.php?p=40974831#post40974831
if we ever get to the point where we don't need 3g at all any more (CDMA) and we can get VoLTE and use the LTE band exclusively that will eliminate a lot of the incompatability between Verizon and GSM carriers .

When we get to that point, Verizon will basically be a GSM carrier. Considering LTE is just an evolution GSM, both developed by 3GPP.

When it gets to that point, the question is will LTE then become open so Google can sell a Nexus that works on every network without carriers involved?

Not just Google...all the manufacturers could do it. But...don't get your hopes up. That situation is not in the carriers' nor major manufacturers' interests, and they sit on the standards bodies. No one represents the users/customers.

No need to unlock just go into settings on the phone and under mobile networks their should be a tab that says prefered network.... click it and select global....
