[Q] Samsung galaxy S4 not working on Straight Talk - General Questions and Answers

I just purchased two unlocked samsung galaxy s4 AT&T SGH-I337 unlocked phones. I returned one because it would not read my sim card for an AT&T Straight Talk sim card. I spoke with a ST tech support who told me that the phone should work if it were truly unlocked. The second one is doing the same. Today, I contacted ST and was told that ST would not work with the technology in this phone. This doesnt make since and I would like to get more information. There are ST customers using SGS4. Some one please help me with this because i have a beautiful paper weight.

Try using another SIM or another prepaid plan other than ST ie. H2O

Does the Skyrocket have a SIM socket?

I realise it's a bit of a noob question but I do a fair amount of travelling and would look at getting a Skyrocket if I can unlock it and use different SIMS depending on which country I'm in at the time, I know from previous experience that some of the North American providers 'hard' lock their phones to only their networks.
I currently am carrying a i9100 SGS2 which I'm pretty happy with however I'm also looking at the GNote and perhaps any other Samsung phones that support 4G(LTE) and will let me swap SIMS.....all suggestions and comments welcome.
Yes it has a sim card slot

I believe all GSM cell phones have SIM card slot(s). I am thinking to get the AT&T Samsung Skyrocket phone. But I am wondering about your statement/question ("if I can unlock it..." to use other carriers' (local) SIM cards while on travel outside AT&T service areas.
Has anybody succeeded to unclock it? And how?

If you have been a customer with AT&T for some time they will give you an unlock code if requested.

It depends on the device. If the device is new to AT&T they might not release the SIM unlock code. I have been with AT&T since they took over from L.A. Cellular and AT&T would not give me a SIM unlock code for my Infuse a month or so ago. The Customer Rep gave some BS excuses. Luckily Rooting and unlocking the SIM could be done without AT&T.
The Skyrocket is a different story, I am also interested but could not confirm that it could be SIM unlocked.
Some folks reporting some paying service could do it and some said they do not work.

US based Phone going overseas

Ok so here it is in a nutshell. I spend half of the year in New Zealand and Half in the US, in new Zealand I am on a GSM network and have had good success unlocking IOS devices (AT&T) and buying a prepaid SIM card and using them there. I want to pick up a Samsung either a S2 or S3 and use it over there as I am just sooooooooo sick of IOS. with all of that being said. I have a few questions and I did a bit of looking but not sure.
I have a HTC Thunderbolt for Verizon (yes I realize it CDMA and wont work on GSM) and have rooted it and flashed a custom ROM on it so I am not unfamilliar with the process.
so first question
1. Do you have to Carrier Unlock Android OS phones like you do IOS devices Or do you just root and flash a new ROM to it?
2. Do all of the US based GSM carriers have SIM card slots? (I know the IOS devices on AT&T did.
3. If AT&T phones work over there will sprint and singular will work as well?
4. Since I will not be using 4G over there am I better off with the Galaxy S2, I was also looking at the Nexus as well any thoughts?
Guys I realize that there are probable 20 threads with the same questions or a variation and I have done some looking but with everything happening in my life at the moment I don't have a lot of time to make decisions about phones.
thanks.
I'm going to answer this as best as I can. A CDMA phone overseas isn't usually a hot idea. A gem phone will typically have a sim card in fact I haven't seen one that didn't... and still fell into the gsm umbrella. Get an unlocked device as the only way a CDMA phone overseas will benefit you is if you find a CDMA phone company in aus and flash it. But again gsm will be the easiest way to go. Its a T-Mobile phone call and say you want a sim subsidy unlock (current active and not past due tmobile customers only) can take up to 14 days for the code.all the phones you will get in USA will need a carrier unlock unless a software one is available. And I'd go with the galaxy s2 just because it has some beastly ROMs and great longevity

ok just to be clear I won't be using CDMA overseas jsut GSM. does the Galaxy S2 have software unlocks?

Also most CDMA phones don't also come with a simcard slot. Gsm is your best bet so get your galaxy s2 with T-Mobile or att

Is it possible to put a unlocked Verizon s6 on straight talk?

I can't seem to find a straight answer on this. If I buy a Verizon S6 without a contract can you place it on Straight talk? I see that they sell Sim card for lte so I am under the impression you can but can't verify

HERE is a discussion on that network.
Thanks but that doesn't really help. I don't want it on the att network, straight talk also uses verizon towers with CDMA phones. I'm just checking to see if anyone here has done this yet with this phone and straight talk since they now sell lte CDMA Sims.

you must be talking about some Straight Talk i have never hear of because the national Straight Talk Wireless which you can see on their info page here where it says :
Which phones are compatible?
The Straight Talk SIM card will only work with an AT&T or T-mobile compatible or unlocked GSM phone.

It should work

I can confirm that Verizon's S6 works on Straight Talk (AT&T sim version). You will get calls, messages, and even LTE data. The only downside is that incoming calls will be prefixed with + (plus) which breaks contact matching: e.g. if you are getting a call from 650 000 0000 then it will show as +650 000 0000 and it will break contact matching (it will look as an unknown number).
Ok this is what I'm talking about, a CDMA phone using this lte sim that they sell for Verizon phones. They fit right in and supposedly give you LTE, it's new this year

Yeah apparently no is aware of this yet online..... I do think it will work thought I found one guy on you tube that used the cdma sim for his verizon iphone.
I am very curious I mean obviously it has to work or else they are selling false cdma sim cards lol. There byop system says my vzw s4 is compatible now which use to it did not.
For the people who still think straight talk only sales att tmobile sims look here you are wrong shopstraighttalk com/bpdirect/straighttalk/Start.do?action=view&siteType=TR&gotoPhonelist=true&productFamily=CDMA%20BYOP&market=CDMAV&locale=en[/url]
also page plus offers 4g lte sims for verizon also. Im about to buy a verizon gs6 off ebay use it to finish up my remaining 4 months of contract with verizon and the switch.

But that pic you linked MACHEK I do not think is the right kit the one in the youtube video and at my walmart is much diffrent
For what it's worth, i have a straight talk cdma SIM running in my Lumia Icon which is a verizon phone/
This definitely will work, I purchased a galaxy s4 verizon version, and put it on straight talk. You have to purchase the correct sim kit (the red one, not the blue one). The only thing is they limit the speed of the LTE to around 5 mbps download.

I would recommend the new Verizon prepaid plan, it is slightly more expensive than straight talk ($45 for 1 gb, extra 3gb is $20 but rolls over for 3 months), but it is real verizon and unthrottled 4G speeds.
On another note, post pay verizon = american customer service. Prepay verizon = foreign accent/hard to communicate customer service. Its not as bad as straight talk's though
Yes it will work No need for unlocking .. I just purchased a S6 edge from verizon NOT UNLOCKED .. and just used the SIM for Verizon through Straight Talk! So all is good! No enjoy that beautiful phone!
I just received my unlocked Verizon S6 in the mail today, threw my Verizon ST sim card in it and it jumped right on no problems at all

T-Mobile Galaxy Grand Prime on MetroPCS???

I currently have a T-Mobile Samsung Galaxy Grand Prime (SM-G530T) and I am planning on switching to MetroPCS' $40 plan.
I have tried searching Google with mixed answers.
Anybody know if I can switch to MetroPCS and get a SIM Card and use it in my T-Mobile phone?

You do know T-Mobile owns Metro PCS, right?
As long as it's SIM unlocked.
Yes I am aware T-Mobile owns MetroPCS that's why I asked because I tried my Family Mobile SIM in a MetroPCS phone I found and it didn't work at all yet there's a video on YouTube that shows MetroPCS working on a locked T-Mobile iPhone 5s although I don't think it was actually locked..
Turns out family mobile locked their phones now and i switched to cricket, gave that phone to my mom... Luckily it was one of the last fammo phones to work with a tmo card

How unlock used Samsung Galaxy Book 2 (Verizon) so I can use T-Mobile SIM??

How unlock used Samsung Galaxy Book 2 (Verizon) so I can use T-Mobile SIM??
My friend bought a used Galaxy Book 2, put in his t-Mobile Sim and message came up that stated something to the effect that his device needs a Verizon Sim. Even with this message (as someone said it still worked) it did not get a signal.
He cannot return this as he bought it from some 3rd party he will never see again.
He has T-Mobile as a carrier for quite a few phones and has some sort of lifetime extra device -T-Mobile sim plan he can use so he does not want to move just this device to Verizon.
The question is can this be unlocked by Verizon store? And even if it is and APN settings are changed would it work with a T-Mobile Sim?
I know nothing about these LTE laptops and not sure at least for Samsung if the radio in it is somewhat universal or compatible with most US carriers.
Thank you for any advice.
I appreciate it.
Sincerely
Peter
