Absolutely no way to run a Verizon Sim on i337? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hey XDA,
I'm thinking of switching over to Verizon due to corporate discount. If possible I would like to keep this phone and just use the Verizon Sim card with it. If not, I'm planning to trade this phone for a Verizon gs4.
Is there anything that I need to watch out for if I'm buying/trading off of Craigslist or eBay?

Nope
Absolutely no way possible Verizon is on a totally different network setup they use CDMA technology AT&T and T Mobile use GSM the only reason why Verizon is using Sim cards iAbecause they use it for LTE purposes only I've been there and tried it let me save you a headache of asking lol

[Q] Droid Pro on Tmobile or AT&T in the USA

i have been reading and searching for over an hour now here and on several pages and do not seem to find any answer froma real proffessional.
why i cant get signal after i insterted my Tmobile Sim card in my unlocked droid pro verizon ? i even tried and insterted my co worker AT&T sim card, same results, NO NETWORK FOUND.
Verizon told Motorola to block GSM networks inside the US. There is nothing wrong with your phone, but right now AT&T isn't going to work.
Check out the Droid 2 Global forums for more info. I believe folks over there are working on a solution.
Have you had the GSM antennas unlocked? When I bought my Pro I was told that in order to actually use it in Global mode (and use the GSM antenna) you have to either take it to a verizon store or call a number for them to unlock it. The GSM antenna is disabled by default.

The GSM antenna is not locked by default, but the SIM card slot is. If you wanted to take the phone to Europe and buy a pre-paid SIM to use over there (instead of Verizon's SIM) then yes, you must unlock the phone.
However, entering the SIM unlock code will not help you connect to AT&T or T-Mobile, because Verizon blocked it on the radio level.
GSM antenna unlocked?
i am not trying to be Jerk, but i have been in the cell phone repair business since 2003, and never heard of that term, is that a new term?

that's what i was told by a sales rep at the verizon store, so it came from a totally reliable source.
maybe I just got confused as to which was locked (sim card vs antenna)

The sales rep is a retard. Lmao.
Man, if the unlock has truly been discovered, it's going to be real tempting not to switch over to T-Mobile if Sprint lets me out of contract. I use my Droid Pro strictly as a travel phone, but if I can use it at home, too, I'd love to.
Unlocked Droid Pro for USA GSM!
This other guy on androidforums came across an unlocked DroidPro that worked with his T-Mobile Sim Card for a while until he decided to update the phone and ended up blocking his T-Mobile sim card in the end...
I kind of hope there are some other phones like that out there so I can get my hands on one of them and figure out where to look for that piece of code that blocks the phones ability to use T-mobile/AT&T networks.
I use my droid pro overseas, but travel to the us two or three times a month. It sucks to have a global phone that i can use everywhere (roaming) but not in the US. A verizon plan is simply too expensive to afford to use 4 days a month.
I would be willing to pay, donate, contribute to find a way to activate the droid pro on a prepaid at&t plan. Or even an affordable verizon daily prepaid plan. Any ideas?

You could have it flashed to Page Plus. They operate on the Verizon network.
anyone know if it's successfully been done? Have an XPRT and we might be migrating from Sprint to Tmob. Would love to keep using the XPRT as backup phone or primary if it takes a while to get my hands on Milestone 3.
It won't work on T-Mobile 3G, and I don't know if this works for the XPRT, but the Pro unlock has been released.
http://forum.xda-developers.com/showthread.php?t=1259550
well that's a waste. Too many damn gsm bands. Thanks for the link. Might do it anyway. If I end up selling it, it'll be more valuable if it can be used on AT&T. Think getting GSM phones from Bell Canada is the way to go for Tmob phones. Think the Milestone 3 will be in my future if we do the switch.

[Q] Using VZW G2 internationally

Does anyone know if I will be able to use the VZW G2 internationally on a GSM network by swapping out the SIM Card? Let's say I'm going on vacation for 2 weeks...would I be able to buy a SIM card locally, pop it in to my G2, and just pay as I go while I'm down there? Sorry if this is a dumb question, but in my experience the older VZW CDMA phones couldn't do this

the Verizon sim slot as far as I know is for a 4g LTE sim, the GSM HPSA+ frequencies I dont think are active, and even if they are it's likely sim locked.

S4 with Straight Talk - Verizon or T-Mobile

So I need a phone for a while on a pre-paid cash only plan. I was going to pick up a straight talk card from Walmart. I have 2 old Samsung S4 phones from Verizon and T-Mobile. Will the sim card activation chip I get work on either one of them, or does it have to be specific to the previous carrier. Is there an advantage to going with one or the other. I would prefer to put my own rom on there if possible since it is such an old phone. Is one going to be better suited than the other. As far as I know, both phones are out of contract. I know for sure the Verizon phone is already unlocked via verification from Verizon.
Thank you.
If you're buying an activation package from WalMart ($45 airtime card plus SIM), it should come with multiple SIM cards for Verizon, AT&T, and T-Mobile. Thus you can use the service on any phone. If it doesn't, you'll likely have a GSM SIM, meaning you would need to use the T-Mobile S4 to get service.
The advantage to using Verizon is access to Verizon's network, which is the largest in the country. The disadvantage is that your LTE speeds are throttled to 5MBps. With T-Mobile, your network is much smaller, but your LTE I don't believe is throttled. I personally would take the time to carrier unlock your T-Mobile device (see the thread we have on unlocking phones in the General section), and then use the AT&T SIM. With AT&T, you get a network nearly as large as Verizon, plus LTE is not throttled.
As to ROMs, you're simply going to have to try them. Regardless of the ROM you use, so long as you know how to set up an APN in settings, you're good. Straight Talk changes their APNs from time to time, and the ROMs don't always use the latest APN.
Very good information and exactly what I was looking for. One more question on that if you don't mind. If I start out on Straight talk with the AT&T, can I switch over to Verizon a week or two later effortlessly, or would I need to do something to switch sims?
I do not know how to change APN's, but I am sure I can find the answer to that using search.
Thank you.
If you wanted to switch over to Verizon from AT&T, you would need to transfer your service from the AT&T SIM to the Verizon SIM. To do this, you have to go online to Straight Talk's website. Now, while they do offer an automated procedure to do this, the best thing to do is open up a chat window to one of their support reps, and have the support rep process the service swap.
Keep in mind two things.
Once you switch SIM cards, the old SIM is no longer usable. Should you change your mind and want to go back to AT&T, you would need to purchase an AT&T SIM off Straight Talk's website. They normally charge $15 plus shipping for the privilege, but if you hit it right you can often get the SIM cards for a dollar plus shipping, which is somewhat more palatable. I will say that when you get your next phone, you'll likely have to get a Nano SIM. However, you can then go onto Amazon and purchase a SIM adapter, just in case.
I am a person who believes in getting everything that you pay for, and with Verizon, a throttled LTE service doesn't qualify as getting everything that you pay for. Thus, I do not recommend switching to Verizon, ever. Stay with AT&T.
Ok. Good advice. Thank you.
The only reason I wanted to try both was because I am in a high rise where service can be sketchy. Not sure which one will work best up here. I currently have Sprint which does not work at all.

Is my sprint S8 seriously locked to sprint FOREVER?!

Hi guys.. So I bought a Samsung Galaxy S8 from Best Buy Mobile last month. I had to use sprint because at&t (my fav. carrier) would not finance me on the phone. I was told if I paid off the phone I could switch carriers. So that's what I did. Sprint even unlocked it. Now people are telling me I can't use this certain phone on at&t, or even verizon because it is a cdma phone. No one told me this when buying the phone.
Is it true that I am stuck with sprint?! I have horrible coverage in my area and I can't even use the internet and such unless I'm on a wireless connection. What can I do? Please help!
Did you try putting in a non sprint sim?
If it is SIM unlocked, just flash the unlocked (G950U1) firmware on it.

If the Sprint unlocked your phone, then it won't hurt inserting another sim in it. Theoretically speaking it should work and if it won't, then flashing is another way of making it work.

Who are these ignorant people telling you this and why are you listening to them?
1) Verizon also uses CDMA, so having CDMA is the reason it WOULD work with Verizon.
2) All the carriers in the U.S. get the same phone. All the bands needed for a specific carrier are activated when the SIM card is installed. The only reason it wouldn't work is if Sprint had not unlocked the phone after you paid it off. It would be locked to Sprint to prevent you from not honoring the purchase agreement. And even then it would be blacklisted on Sprint network, if you didn't honor the purchase agreement.
3) if inserting the SIM card for another carrier doesn't automatically change the firmware, then do what this guy said:

Sprint, at&t and even verizon said my phone wasn't compatible even after I told them sprint unlocked it. I had no idea about all this cdma, gsm crap when buying the phone. I have never had a decent phone like an S8. All my phones have been cheap prepaid phones since now due to the fact no one would ever finance me for one. I was SOO freakin surprised and happy when someone actually agreed to finance me, I figured I could pay off the phone and then switch. After paying off the phone is when these companies said it was incompatible. Weird thing is I went to IMEI.info and it says it IS compatible and IS unlocked for sure. I then went to at&t online and after typing in my imei number it also said it was compatible. I'm so confused. I am going to take it up to at&t tomorrow and see what happens when I buy and insert a sim card. If it turns out to be sim locked is there a way to bypass this? I truly have paid the phone off and after doing so I asked sprint (on the phone) to sim unlock it, they said they did.
Please do not listen to the idiots at the mobile companies. There is ZERO difference in the S8, ZERO!!!!! If It's not sim locked it will work on ALL carriers, both cdma and gsm.
If It's still sim locked, some people have had success paying a third party to provide a code. But I would try sprint first since They said it should be unlocked.
My guess is that it will work fine with another sim card.
I would either flash the att firmware or the unlocked firmware on it.

Should I flash the att firmware before inserting the sim or only if the sim does not work? Also is there a way and should I back up my sprint firmware or should I be ok? Thanks.

If you bought it from Sprint (or even just used it on Sprint), then you have a Snapdragon 835 S8. Only the Snapdragon variants have CDMA bands for Sprint and Verizon. Only the Snapdragon S8/S8+ variants are sold by carriers in North America -- so they can be cross compatible with Sprint/Verizon/AT&T/T-mobile/Canadian carriers. That's why whoever told you this nonsense is so ignorant.
If you had IMPORTED an Exynos variant from like England, then you would be limited to AT&T or T-mobile. But you have the "universal" Snapdragon model. Now the Exynos variant has an easily unlocked bootloader, which is a reason people import them, but that's another topic altogether.
As long as your Snapdragon 835 S8 is SIM unlocked (you have paid for it in full, and Sprint says they have unlocked it), you can take it to any other carrier or even an MVNO (like Straight Talk) and use it.

Since you phone is paid off, when you go to AT&T, try AT&T Prepaid (formerly called GoPhone). It's really for people who already own their phones.
Same high speed data off the same low-lag data servers used by "contract"/postpaid AT&T customers (with one exception, which I'll warn you about),
same in-store AT&T customer service as contract/postpaid AT&T customers,
same AT&T SIM card as contract/pospaid service. (The store may have SIM cards labelled "AT&T Prepaid", but underneath it's the same AT&T SIM card. If they try to charge you for one, tell them you want the FREE AT&T SIM card. It's the exact same thing.)
Make sure you go to an AT&T corporate store, not a "franchise" store. At the AT&T corporate store they will even give you free AT&T SIM card to use for AT&T Prepaid. (Franchise stores will try to sell you SIM cards.)
The advantage is AT&T Prepaid is much less expensive service than "postpaid" AT&T (contract service). Since you already own your phone in full, all you need to pay for is monthly service. You don't need to pay extra each month so you can get a "free" upgrade to a new phone in 2 or 3 years. (Not free, you are really paying for it with extra fees each month.)
You would want the $45/6GB plan on AT&T Prepaid. Do not fall for the $60 "unlimited" plan. The $45/6GB plan gives you plenty of UNCAPPED high speed data/unlimited calls/unlimited texts. Whereas the $60 plan caps your data speeds at 3mbps to compensate for it being "unlimited". AT&T Prepaid uses same data servers as their AT&T postpaid customers and I get ping speeds often less than 30ms, most often 26-29ms, which is fantastic low lag speed. (Lower pings are better, lower ping speed = less lag). If you go to even a service like Cricket (owned by AT&T, but you won't see any AT&T logos anywhere), they use proxy server farms and you often get triple digit ping speeds (high lag). This is also why Cricket has to use a DIFFERENT SIM card from regular AT&T. Higher ping speeds make it seems like your download speeds are much slower than they are.. due to LAG. Plus Cricket caps ALL download speeds at 8mbps. Until AT&T Prepaid (formerly called GoPhone) introduced their $60 "unlimited" plan, ALL their plans were uncapped high speed data. They didn't cap download speed at all. But now they have started capping speeds with the $60 "unlimited" plan. So STAY AWAY FROM THAT.
With the $45/6GB plan, if you autopay each month, you can save $5 and only pay $40 per month. So, $40 per month for 6GB data, with UNCAPPED low lag data straight from AT&T. Don't let them charge you for a SIM card! AT&T Prepaid uses the exact same SIM card as "regular' AT&T.
If you decide you don't like it, for whatever reason, you can switch to "regular" postpaid AT&T. But since I always pay for our phones in full, I like to save on monthly service. Although there are tons of MNVOs with prepaid service, they all use proxy servers with high lag (high ping speeds). Even AT&T's own Cricket is configured as an MVNO, to compete with MNVOs like Straight Talk. But AT&T Prepaid is not. It's "pure" AT&T, but at budget prices -- which AT&T uses to compete with actual carriers like T-mobile and Sprint.
You can "bring your own phone" , which in this case is your fully paid for Galaxy S8.
How do I know which ones are the corporate stores and which are the franchise stores? I'm looking at the St. Louis map now. Some say at&t authorized retailer and then some just say at&t.
I have a sprint model and I unlocked it.
It works with T-Mobile and gets LTE
It works with att and gets LTE
It works with Verizon my current carrier now and also gets LTE
Highly recommend flashing the unlocked software if you go this route the sprint software with non sprint SIM cards is very annoying.

It worked! Thank GOD! In my room now I get -90/-100 with att and had -100/-125 with sprint. It is using HSPA and I can't find LTE on here to switch over. It stays on 3g, it never goes to 4g or LTE, how can I fix that?
So please tell me what I need to do to delete the sprint crap on here and put att on it. Thanks guys.
Not being rude, but you've been told many times on here What to do , reread the posts.

Ok, so I want to do the prerequisites - check.
Then just do the carrier switching part and I'm done right?
Do I do all this with the sim card installed or not installed?
Sorry, this is my first time doing this.
Ok, I did what the guide said. During the flashing standard firmware part after clicking start is said FAIL! SHA256 is invalid. I ended up going back into ADB, rebooting and trying a different att firmware download and now the phone works. Weird thing is, I don't see alot of the apps that I had on an old phone with go phone and 4g LTE is not working, it's not even an option. What should I do if I want to wipe clean the phone to stock samsung android, not stock sprint as I bought it. Then I could insert the new go phone sim and it will install those apps and turn on 4g LTE? I'm learning guys, slowly but surely. I love this kinda stuff, so please bear with me here.

Authorized retailers are code for "franchise stores". They are not owned by AT&T nor run by AT&T. They do not have actual AT&T employees and they will nickel and dime you for every little item, like SIM cards. Whereas "corporate" AT&T stores will give you free AT&T SIM cards.
When AT&T Prepaid was called GoPhone, event the AT&T stores sold a GoPhone SIM card "kit" that had various sizes SIM cards with plastic shims for $15 -- which was totally unnecessary. I just told them, "NO, I want a FREE AT&T SIM card which fits my phone." And at the corporate stores they have to give it to you. AT&T and AT&T Prepaid (formerly branded as GoPhone) uses the EXACT same SIM cards. It's just they had some "labelled" as GoPhone but underneath it was the exact same thing.
3or 4 years ago, I had a friend buy a brand new Samsung Galaxy phone "on contract" INSIDE an AT&T corporate store, then immediately paid it off with his credit card, and switched to GoPhone -- all in the same visit -- and they did NOT even touch his AT&T SIM card inside his phone. It's just an internal AT&T accounting change. Now GoPhone has been re-branded as AT&T Prepaid to make it less confusing.

H918 question: possible to do bootloader unlock and root work without SIM card?

Hi,
I'm wondering whether it is possible to do bootloader unlocking and root work without SIM cards in the H918's. We currently have VZW service and VZW phones that we will be dumping and porting over to T-Mobile. I am lining up some H918's that are network locked but I don't think they will come with SIM cards.
I know we will need T-Mobile SIM cards to be able to get T-Mobile service, but I am wondering if it is possible to do the root/unlock/ROM work etc. without the SIM cards in and before we bring our phones in to have our VZW service terminated and the cell numbers ported over. Seems to me like the T-Mobile store is not the place for me and our new phones to be if our phones start pulling in an OTA as soon as they are activated on the T-Mobile network... I suspect they just wouldn't understand why I don't want it updating and why I am so serious about that....
Maybe the idea of bringing rooted phones (or phones I plan to root later) in to the store to let them mess with them is a bad idea. Would I be better off to order SIM kits online and sign up for service/switch online? Is that possible?
Thanks. I just want to stop any OTA's from messing up my plans with our new phones.

Don't need to worry about any OTA on the h918. Also don't need a SIM card for the phone. Just follow the noob easy guide and you will be fine.
