Hello, I currently have Sprint in the USA and locked into a contract but when travelling, the service is spotty. I have to take a 2nd phone that I have with tmobile. I understand I can buy like a new Sprint iphone or the new nexus and just swap sim cards and that will work? That is one option. I was also wondering if there is like a single phone that will work with both sprint and tmobile at the same time. Kinda like the samsung duos phones but those only work with 2 gsm carriers. Tried a search but didnt get anywhere. Thanks. Just weighing my options here.

Not with Sprint. As you've no doubt seen, dual SIM phones aren't exactly common in the US. The few that are are imports, and fewer still will even support North American GSM bands. And of course, Sprint uses CDMA for telephony, and only Sprint phones work on their own network. Your only option would be to switch to AT&T and/or T-Mobile or their MVNOs that work on those networks, and find the rare phone that has LTE for both. But if you're sticking with Sprint, you'll either have to swap SIMs on a device that works with any (as you said, iPhone, Nexus...I think the Moto X Pure does too), or carry a 2nd phone for a different carrier.

I am currently using the phone as a pure wiiFi item. I will be coming out of contract with them and do not plain to get a nother contract. I know that att has a pay as you go for $.10/min with a $15 for 100mb. Belive it or noth that is enough for me for data as I normly only us the phone for about 20 min and 10-15 mb a mounth.
What I was woundering is if I unlock the phone are there other carriers I can go to with this phone so that I can compair? Thank for any help on this.
Yes, when you unlock you can choose any carrier of your choice
Big Dog Infuse I997 ICS CatyRom
Which country are you in? You basically need to check what bands the carrier you want to switch from uses. They need to match what your infuse can use otherwise it won't work.
The phone supports: UMTS 850/1900/2100 and GSM 850/900/1800/1900. I think T-mobile runs on a different band but I don't know for sure as I live in Canada. Here in Canada you can use this phone on Rogers (the carrier that sells it), Bell, Virgin, Fido but I don't think it will work on WIND. If memory serves me correctly it might not work on T-mo, Verizon or Sprint (because Sprint and Verizon are on CDMA). If you are in the US you might want advice from someone other than me though.

yeah but umts bands are incompatible so you still only get 2g.
Isn't it possible to band unlock the infuse, but it requires more than the typical efforts. wasn't some group offering to do it for $50 if you send your phone to them?
Straight Talk. Uses AT&T's networks. But you have to buy a phone off of them with a sim.

There are different types of carriers in America and there are many things scarier can,do to lock certain devices to the network. Tmobile and att are gsm carriers and have some compatibility But they use different bands. The talk works and edge works. No 3g.
Sprint and Verizon are cdma and are not compatible. However Verizon,has phones that are both gsm and cdma and can,work on att. Nextel has Sim cards but are iden. Boost is also half cdma and half iden. And begin is basically sprint.
Then there are the no contract deals like strait talk. Problem is the Sim may be locked to the phone and even if you know the phone has a Sim and is working off atts network it may not work. The strait talk thing is only known to work if you buy a $200 Nokia smartphone and many of those have Tmobile Sims that are locked to the phone. I'm not sure how to tell the tmo version from the att version without looking at the Sim itself. Strait talk seems to just buy rights to use other networks, I've seen phones at Walmart with gsm on the box and others with cdma on the box. I think they use all the major networks depending on the phone.
I also saw an ad for simple mobile. Seems promising but appears to be Tmobile
So no 3g.
In Canada almost all carriers are 100% compatible with att phones. All but one but I forgot the name. So if you're Canadian you have options.
Do not know if you know about this- New T-Mobile Monthly4G $30 Unlimited Web & Text with 100 min of talk
email delivery or purchase monthly cards at Super Walmart.
Can not post link but go to Walmart dot com and search for the card I listed above.. sorry
Consumer Cellular is an AT&T reseller - in fact AT&T phones treat their SIMs as an AT&T SIM, don't even need to unlock.

Thanks, good to know. Might have to look into a consumer cellular Sim and an i777. I wonder if it will work with lte in the future (the Sim that is. not the phone) but I can,worry about that when my area gets lte and the next generation,phone comes out.
Not too long ago, I had heard that the Verizon Galaxy S3 would support global roaming in a future update. With the Verizon Galaxy S3 release imminent, I was wondering if this was still the case.
I recently ordered a Galaxy S3 for my Dad, considering his contract with Verizon was up and the data plans were changing. Now, my dad often travels back and forth between the US and South Korea; so often in that he carries two different Android phones for each country (DROID Incredible on Verizon and Nexus S on KT).
Would it be possible for him to dump both the Incredible and Nexus S phones and use only Verizon Galaxy S3 on both of the carriers (if unlocked), by just swapping out the SIM card when traveling between Korea and the US? He will be keeping KT as his cell provider in Korea and from what I've heard, KT does allow foreign phones to be registered on their network, as long as they're unlocked. Both Verizon and KT support CDMA & LTE, but I'm not sure if their frequency bands overlap and if the Verizon S3 would be able to hook onto both without having to flash the radio.
I see that there's already a Voodoo S3 SIM Unlock app on Google Play (probably not compatible with Verizon S3 yet, but maybe eventually possible?).
Either way, it'd be awesome to be able to use the S3 as his main phone on both carriers with a simple SIM card swap! Does anyone have any insight on this, whether it would be possible or not?

As far as I understand it, the Verizon S3 needs a software update to unlock the GSM bands within the radio, which currently is not available...Also the LTE Bands are Not Compatible, according to my research Verizon uses 700/750 KT uses 1800. The Verizon S3 has 700/750 LTE Support...Also note while the Verizon S3 likely will have GSM support via a software update it will be Edge bands not WCDMA/HSPA+...as for the CDMA side out of luck there too according to KT they use the 1800 band and the Verizon S3 only has 850/1900 band for CDMA...in short getting the Verizon S3 will in no way help your father ditch his second phone...If your father is an international traveler he would be better suited to using a GSM carrier then buying a phone like the Galaxy Nexus which is pentaband WCDMA, this will work in any country that has WCDMA, I can vouch personally that my GNex (GSM Unlocked) works in S. Korea with HSPA+ Data Speeds as I was just there this past February.
So though the GS3 would most likely not be able to use 4G (through HSPA+, I may also be misunderstanding...) would it be able to have 3G overseas? I ask since I will be traveling to China later this year and being able to use 3G over there would be more convenient than getting another phone...
I just bought Verizon Samsung SCH-I705. I just wonder that can it could be unlocked to use Tmobile SIM. I know that this one has LTE SIM but just wonder?
I'd like to know the same
ill like to know that too

This has been asked before and the answer is still the same
Verizon - CDMA Carrier
TMO - GSM carrier
Two different radio's. You can use an unlocked TMO tab and use it on AT&T (Another GSM carrier).. The Verizon tab shouldn't have a SIM card in it. Unless it is a World tab or LTE. In the LTE case, only the 4G is sim controlled, the 3G is controlled by the CDMA radio.
Verizon:
Frequencies and Data Type Digital: (CDMA/PCS)/1x, EVDO Rev A, LTE (Band 13 only)
Tmobile
Frequencies and Data Type GSM: 850/900/1800/1900
So your answer is no.....

I believe you answer is just partially correct. My Verizon Tab has a SIM slot. I currently own a Verizon Iphone 4S, Iphone 5 and Samsung S3. Used to own BB Tour, Storm, Bold, HTC Incredible 2, HTC rezound. After unlock, all of them (they have both CDMA and GSM) can be used with any SIM card. That why Verizon called them Global Phones. I also believe that the Samsung S3 is LTE phone with SIM card slot and I have no problem to use it with my TMO SIM card

My US Cellular S3 had a SIM card too, but USCC is a CDMA phone. The SIM card was for 4G LTE only as USCC is a CDMA carrier. Some of the BB was "World Phones" meaning that they had 2 radio's in them, 1 CDMA when you was in the USA, the other was GSM when you traveled outside the USA but could not be used inside the US unless it was (the GSM part) unlocked. I know there are some other Android "World Phones" I had the Motorola Electrify, I think it's counter part on Sprint had a different name. There was a few more on USCC that was World Phones, They had dual radio's. But the S3 and Note 2 didn't. But I would guess that it could be possible that Verizon's variation could be different. I never looked that close. But if there is a way to unlock it and use it on a GSM network, then do a search, the phone is old enough to have already been unlocked, and a search would turn it up if it was. If your search comes up negative, then you will have your answer.

Thx for your reply. My Verizon Samsung S3 was unlocked by Verizon (by agreement from verizon with FCC) as they did with Iphone 5 (can be considered as factory unlock). Both of them can be used with GSM carrier here but not the Iphone 4S (for abroad use only even it is unlocked by Verizon).
I searched and have not seen any solution for unlock the Samsung Tab I705 in US but there are unlock code for sale for I705 in Europe and in Asia. I checked the I705 specifications but only see LTE 700Mhz, Class 13 (as you stated) in your previous post. Same thing with Verizon Samsung S3 I535 but I can use S3 with TMO sim. That is the reason I want to find out anyway we can unlock I705 (Tab 2) to use with SIM card for GSM carrier. Anybody can help?
DAMN!
I was looking for the same thing!
>.>
yes it can be done
I know that the verizon galaxy tab 2 can be unlocked. A friend of mine had verizon do it by claiming they where traveling outside the country, and it works on T-Mobile just fine. because it does have both radios. PLUS i want it for the LTE anyways and it does work for the t-mobile LTE. problem for me is that i no longer have an account with verizon so they will not give me the unlock code for the tablet so i need another way to unlock it.... can i do this by rooting it and putting a customer ROM or does that no effect that portion of the tablet.

I have Samsung Tab E Verizon SM-T567V it's Global and 4G supported with a dedicated sim slot. How to sim unlock it???
The phone is only $99 on Verizon. I heard you needed to use the phone for 6 months before you can use it on another carrier
Anyway to get around this or has anyone actually done this yet? Want to make sure it works.
And are you still getting Verizon coverage on Straight Talk or how does that work?
Is there a 16gb CDMA version as well? Only saw an 8gb.

I think that Straight Talk is a GSM network so you would have to have the GSM model of the phone. I was under the impression that Straight Talk uses the T-Mobile network. Someone correct me if I'm wrong please.

They have a CDMA card you can buy and register your phone on their network. I think it's kind of new. I'd link you but I'm on mobile

Straight talk uses Sprint and Verizon CDMA networks as well as T-mobile and AT&T GSM networks...
I'm really not sure how the BYOD on CDMA works, I would like more info as well.

Straight Talk (Verizon Wireless - CDMA) will require an access code to their network; $15.00. This applies to phones that do not have a SIM Card which the $99 8GB Motorola Moto G CDMA variant is. However, I did put the MEID for the device as to its compatibility on Straight Talk and was told it is not which makes no sense given if you have a GSM variant, it does not require a subsidy unlock code if the device is set up with either the AT&T and/or T-Mobile radios. I have to believe that the reason has to do with those stupid clauses which carriers have with their phones and however long they are. It's always been my understanding the code is what you need to run on their network. One caveat; I have noticed that on Verizon Wireless's prepaid "Everything" plan, the devices run only on their 3G network nor am I aware they have the 4G LTE radios in them. I've tested their 3G band and at best regardless of where I have tested it between Albany, GA; Columbus, GA; Auburn-Opelika, AL; the best speed I have had is tops 1.0 meg down but normally about 0.7 megs (700 k) down...enough to run Pandora or any music app. I will say one thing about the phone, for the price, not bad! I wish it was available when I bought an HTC One M7 I paid $650.00 for but I got the DE 64GB variant; this device, you do feel the 8GB restriction though there are many cloud options.
I currently have a z flip 4 with us cellular and a pixel 6 pro on Verizon, I want to use my Verizon and us cellular number on the z flip 4, kinda like dual sim but the Verizon one as my eim but I keep running into roadblocks, Verizon says it can't be done without closing off my account and us cellular does the same anyone figure out how to get past this?
I am with US Mobile. ( Verizon's MVNO ) I activate my number with eSim with them to get up and running quickly. Then I am able to switch to the real SIM after I receive new SIM order. My guess doing reverse should be the same with US Mobile. I am not sure why Verizon not able to do this without closing account.
On tmobile they set me up to esim, no issue. VERIZON may not be fully supporting esim on androids yet, I had Spectrum which uses Verizon, and they could not set up my esim.
I was on Verizon since cell phones were invented (postpaid, prepaid, mvno), their service and coverage has gone way down hill, now I get 5g where I couldn't even get reception before. So much for keeping a loyal customer happy.

I've had issues with us cellular using an esim too because they want the physical sim to be the main sim card which I think is rediculous, and Verizon just keep giving me road blocks to getting the number ported
