[Q] Boost Mobile Galaxy S II compatible with Verizon CMDA? - Galaxy S II Q&A, Help & Troubleshooting

I see that radio Shack has the SGS II for Boost Mobile for $279 off contract.
I still have six months left on my Verizon contract.
Can the Boost version be used with a Verizon SIM on their CMDA network?
I'm fine with rooting and flashing the prevailing CM ROM.
Thanks, if anyone has done it reliably.

Boost Mobile model of the Galaxy SII is the Epic 4G Touch. That device has a separate forum. You should ask your question there instead of here.
This post is currently in the forum for the GT-I9100. A GSM device that doesn't work on CDMA networks at all.
EDIT to add: Also, I don't believe Verizon uses SIM cards?

Ah, damn, thought I had done enough research to start the thread. Thank you for the informative post. I was unaware of the model differences, and thought this was the CDMA area.
I have an HTC Thunderbolt on Verizon, which used standard sized SIM for the LTE functionality. I thought that if I could get a SGS II to get me through the next six months, then go elsewhere, it would be worth it.
We can close this thread.

Most models of the SGS II don't have LTE, except for a couple of specific models. And the one for Sprint/Boost definitely doesn't have a SIM card slot. You'd need a donor ESN, from what I understand.

Unlocked phone but no 4g, please help

So I bought a new SGII 1777 for a really good deal. Brand new out of box, etc. Anyways, T-mobile is my carrier. I was able to root the phone and unlock it. The strange thing is that now that my T-mobile SIM card is in this AT&T phone, I am not getting 4g. I am only getting "E" coverage. I followed this guide http://forum.xda-developers.com/showthread.php?t=1286432. Am I missing something? Is it firmware? Kernel? currently, kernel in phone is 2.6.35.7 with Gingerbread.UCKH7. I'm in the US, so if any of this info helps my cause please assist. Any advice/help/suggestions are welcome. Thanks XDA!

Your on E and you will continue to be on E. The AT&T phone dosent support 3G/4G Tmo bands.
You won't get anything faster than Edge with an att phone on T-Mobile. Hardware is the cause.

The exception would be some of their LTE phones reflashed with a T-Mobile radio. Pretty much Skyrocket and Note and that's it.
This is because AT&T uses 1700 MHz for LTE and T-Mo uses it for 3G, and other than the radio firmware the T989 and Skyrocket are almost identical.
Right now, with the exception of the above cases and the international unlocked Galaxy Nexus (which is pentaband HSPA) - only T-Mobile USA phones will get 3G on T-Mo USA. There may be a small handful of other exceptions, but very few non-Tmo devices support 1700 MHz.
Some research could've prevented this. Or just buy the phone made for T-Mobile.

thanks for the quick responses everyone. I just sold the phone for more than I bough it for. Going to get the T-Mobile one like I should have in the first place
Just curios how much did u sell it for? New or used when u bought it?

[Q] What's carrier can the Galaxy S II be flashed to?

Hi a friend of mine wants to trade his Galaxy S II for my Evo Shift. I'm pretty sure it's worth the trade but before I do I wanna know what's possible on it first.
What all carrier(s) can the Galaxy be flashed to?
What's the best performing/fastest carrier available?
And is the flashing process easy?
Thanks in advance

What country? And what model of Galaxy S II does he have? What carrier did he get it from, if any?
There are over a dozen different models of Galaxy S II, and they are all different. Some are GSM, some are CDMA. Some have LTE, some don't. So what carrier the phone will function on will depend on what model it is.
EDIT: You say you have an Evo 4G Shift, which makes me think you are on Sprint, in the US. Is he also on Sprint? If he is, then the Galaxy S II he has is not the same as the one this forum is for.
THIS forum is for the GT-I9100, which is a GSM phone... which means it works on AT&T and T-Mobile (but only with Edge on T-Mobile) in the US.
The one from Sprint (a CDMA network) is the SPH-D710, also known as the Galaxy S II Epic 4g Touch. (Its forum is at http://forum.xda-developers.com/forumdisplay.php?f=1281) If this is true, then I've heard you can flash the Epic 4g Touch to other CDMA carriers (like Cricket, Verizon, US Cellular, etc)... but I don't know the details. If he indeed has the Epic 4g Touch, then you would be better off asking in the forum for that device.
Ok I was not aware of that. But yes it is a sprint version which would make it CDMA. I didnt realize there was a difference between carriers. But thank you anyway for the help!

[Q] Q on Galaxy S II Epic carrier locked?

Hope I am in the correct forum, but have a question regarding the Sprint "Samsung Galaxy S™ ll, Epic™ 4G Touch".
I do not use Sprint, but am under the impression they do not use SIM cards. My question is simple, can this phone from Sprint (Galaxy S II) be used with any other carrier like AT&T? Long story short I have the opportunity to get one of these phones, but my contract is with AT&T.

Probably not. EDIT TO ADD: Sprint is a CDMA voice network. AT&T is a GSM voice network. You'll never be able to get voice on one network with a phone from the other carrier because of this.
And the Epic 4G Touch has its own forum. This is the forum for the GT-i9100. Different phone from the Epic 4G Touch.
FYI though, the GT-i9100 DOES work on AT&T - I have one, and am on AT&T.

Galaxy S3 International works on Rogers?

Hi, I've read that the international quad core version of the Galaxy S3 can be used on Rogers.
I know absolutely nothing about phones so I was wondering how this can be done?
Do I just buy the international version without contract and take it to a Rogers service store and add a plan on it? What type of plan should I be using with the international version? I don't need LTE or 4G. I'm fine with the 3G network as long as the phone works without any issues. Is there any trustworthy sites where can I buy the unlocked international version of the S3?

Rogers is in canada not US :angel:
@OP I am 99% sure that international GSIII will work on Rogers. I had GSII with me and I used it on rogers with a prepaid plan

From a little bit of research, everyone is saying the international GSIII will work as long as it's on a 3G data plan. Is there any downsides to using the international version other than being limited to 3G? Is it as simple as buying the unlocked GSIII int'l phone and using a 3G plan on it?

I don't think there is any downside apart from not being on LTE. Yes it should be as simple as buying an unlocked phone, putting the sim card in it with a 3G plan. In case if your data does not work check if APN is added. I remember it was added automatically for me on GSII
I'm on rogers with the 9300, works fine. Obviously no LTE, but the HSPA+ is fast enough. Not to mention Canadian bandwidth restrictions making LTE a huge turn-off for me. 6GB a month for $60+, no thanks
EDIT: I could be wrong but I don't see a problem with what you mentioned in the OP. Get the phone and just buy a regular smartphone data plan, or whichever plan you want. As for myself, I kept the same plan as my X10 and just cut my sim up because it wouldn't fit and it works fine, no change of plan or anything.

[Q] i9300 and Straight Talk

Any US owners of the i9300 (that's the non-US/International) version of the S3 using the Straight Talk service? I've been looking into them as a way to get some 3G data access for two weeks, but their customer service folks just replied saying that my S3 won't work because it's not a US model.
Looking at the specs seems to show that my S3 will support their frequencies, but I'm wondering if there's some kind of clever device block in place.

I'm using it, it works fine. You need to choose AT&T-Compatible SIM when you buy a SIM, otherwise most of the time they'll send you a T-Mobile SIM if you choose for them to pick it automatically. Also, this wouldn't affect whether or not you get 3G/HSPA+, but make sure when you fill in the APN, you don't fill in any proxy information except for MMS proxy.

Many thanks. :good: I think their CS folks are about as good as the ones for the carriers over here - since their emailed advice contradicts what the website says:
BRING AN AT&T OR T-MOBILE COMPATIBLE GSM PHONE, OR AN UNLOCKED GSM PHONE
Make sure it operates on our compatible frequencies (850 and 1900 MHz)

And according to http://www.samsung.com/uk/consumer/mobile-devices/smartphones/android/GT-I9300MBDBTU-spec the International (UK spec in my case) S3 supports "850 / 900 / 1900 / 2100".
Again, thanks for taking the time out to reply. Maybe see if I can use a local Walmart's click n' collect service to get the SIM+minutes card when I get over to Orlando.

Accidentally thanked you.
Yes, you have to make sure the SIM card isn't for T-Mobile's network. Until recently Straight Talk was only offering this SIM, so your best bet would be to buy an AT&T compatible SIM from their website.

<rant> Verizon and att use different networks, that will never work, especially with a LOCKED phone. Also, this is the forum for the international s3 (i9300), not the verizon s3. </rant>
Pick up the straight talk activation kit, Verizon uses CDMA signal, not GSM.

The Verizon S3 supports GSM though (their LTE devices from the Rezound [2010 or 11] onwards do). Their LTE devices also come factory unlocked out of the box due to a deal that Verizon made with the FCC in order to be able to use the 750 MHz LTE spectrum. Long story short, Verizon LTE devices will get EDGE and HSPA+ (no LTE) on AT&T. It supports the same bands as the i9300.
