Are you implying that you currently have a phone on a postpaid plan, and you want to use it on a prepaid plan? What are you thinking of flashing?

well ill put it this way. my friend wants a nice phone on prepaid. doesn't care about cost. he has 2 phones now. one is on straight talk other is on T-Mobile..he wants a nice phone I was curious if anyone has done it and if anyone had any suggestions on what phone to use with what prepaid. like Sprint Verizon or AT&T iphone 4/5 on tmobile or straight talk. or a Sprint galaxy s3...he'll use just about any new-ish phone.

I guess the 1st decision is what service he wants to go with. Phones are either CDMA or GSM, and not both, with few exceptions (like the new iPhones). So, if he gets a Verizon phone, he can't use it on T-Mobile or AT&T prepaid, and vice versa.
Since cost of the device is no issue, he just has to buy one that's factory unlocked (a.k.a., SIM unlocked).

apologies, I personally have an s3 through Sprint which Ive rooted along with numerous other phones just never did anything of this nature. so I should have him buy a phone that takes a SIM card we'll say and use either straight talk SIM card or tmobile? as an example.

where would be the best place to buy factory unlocked phones? ebay? and obviously the easiest would be to go the SIM card route

If the phone he has/gets is unlocked, he should have no problem swapping the SIM cards, and using the phone on either provider. If you want help mulling over specifics of what particular phone to buy, post it here. You'll get shut down if you start a thread asking what phone to buy.

"Best" is subjective. Some would say to buy it from the manufacturer, as then you would have warranty, return policy, & everything.

well I talked to him and he says he'd prefer to go the galaxy s2 or 3 route. would it be cheaper to buy a unlocked GSM s2? im just confused about the SIM ordeal and what carrier to go with, with what phone. I've tried changing MEID before on a epic to use it on straight talk, which it was CDMA but I couldn't get the MEID to write properly so that was a fail.

Yeah, you don't have to deal with that stuff with GSM phones. That whole "flashing to another provider" thing is a CDMA issue. Basically, any unlocked GSM phone will work, with any GSM provider.
Another thing to consider, though, is 4G data speeds. AT&T (and their MVNOs) and T-Mobile (and their MVNOs) use different frequencies for the highest speed cellular data connections. For example, if you buy an AT&T phone and then unlock it, you won't get 4G data speed on Simple Mobile, since Simple Mobile is a T-Mobile reseller. Therefore, even when you've finally decided which phone to buy, you still need to decide which bands you want it to have, based primarily on which service provider you plaln to go with. One exception to this is the Galaxy Nexus HSPA+, which is pentaband, and can be used just about anywhere, at full speed.

nice. any suggestions for iphone? My apologies. just seems those appear to be the cheapest route via ebay for a gsm unlocked one.

I assume you live in Richmond VA. You probably have a choice between T-Mobile or AT&T 3G/4G. T-Mobile is far better than AT&T and the Monthly Prepaid stuff from T-Mobile isn't bad. I like the $30 plan personally.

There's two 30$ plans (the one with 100min, unl texts and 5GB data and a 1500 min/texts and a small amount of data (30MB?? I forget))
You should be specific. The 5GB data one is only available online or at Wal-Mart.
The other one is available in T-Mobile stores.

Richmond Indiana, my apologies. I appreciate all of the suggestions. I can root phones and such no problem, very new to this prepaid & gsm(sim card) stuff, as I have had Sprint for 6 years lol

so I can order a iphone 3g gsm unlocked for like $120 on eBay (or is there a better place to order them?) and it will work with a straight talk sim card? it's for a friend, im not a fan of either xD

[Guide] At&t Note 3 Sim Unlock

I bought two At&t Note 3s yesterday. One for me and one for a friend. I'm on At&t and my friend is on MetroPCS. I called At&t for an unlock and they couldnt get me a code, even though one was paid in full price and "qualified" to get unlocked according to them. So this is how I got the phones unlocked.
Reminder: I'm not responsible for any damage you may do to your phone. Proceed at your own risk!
Root is Required!
1. To root your At&t Note 3 follow this guide (Thank You designgears!)
http://forum.xda-developers.com/showthread.php?t=2474422
2. You will need to allow unknown sources to be installed.
Settings>General>Security>Unknown Sources (Make sure its checked)
3. Install Chainfire's RegionLock Away App from Google Play Store (and buy him a beer :highfive or download it from here.
http://forum.xda-developers.com/showthread.php?t=2470551
4. Tap "Region Unlock" in the app
5. Let it do its thing
6. Choose Reboot Later (Thats what I did at least)
7. Turn off the phone and try a non-At&t sim card.
I tried my old T-mobile sim in mine and it pulled up, and we just got back from the MetroPCS store and have his running on that.

I have an unlocked note 3 simply I went into the AT&T store where I live and said unlock it or I won't buy it and bam they did it. I have a simple pay as you go T-Mobile card popped it in, input the code and unlocked I was. I had to buy the phone outright so was costly but not at all risky. LTE showed up just fine on the T-Mobile network.

You lucky mother fu
I asked at&t here about that since i bought one full price and they said, to call customer service. So did the next day and they "couldnt" give me the network code. I honestly dont care about an unlock as I'm on At&t.
The only difference is that you're phone wont be region unlocked. Sim unlock and region unlock are different.
Did you buy your phone full price/off contract?

Thats kinda of upsetting. I walked into the store and told them I wanted one full price and they were like "There's no 'full price', its just at&t next and you pay it off all at once if you want". I went online and showed them the option to do full price OR next, and they said they couldn't sell full price in the store. Didn't understand that because my s3 and note 3 were both full price at the store, Plus I've found deals with coupons online and they've matched it before! I hate when I go somewhere and I know more than the person working with me (I think he was just trying to get more commission off me.IDK). : They made me wait longer for the phone than I should've too. Guess my store here just sucks :rolleyes
Kudos to you. Wish that would've happened to me!

I had herd a lot of horror stories like this before I went it but I knew my facts as it seems you do too. An I was just very blunt and studdorn, but also polite. I explained I travel to Europe all the time since I am English and I refuse to pay international rates. An I guess I got the 1 guy in all AT&T that was willing to go to bat for me.

Agreed. Not very happy with this at all. Locking us out of our own devices that most of us paid FULL PRICE FOR!!!

Yeah me too... This sucks... I'm seriously thinking about selling mine and buying a international model. Does anyone know which model works good on At&t?

I bought 2 note 3's and and 1 gear. Dropped about a G and I can't use my device the way I would like? Not a happy customer at this point.

I went to an AT&T store a few days ago to get a secure element for free (SIM) and received a text survey the next day. I gave the employee a 10 but said I wouldnt recommend at&t to a friend, and everything else I gave low low reviews. They called me several hours later and I let them know why... I am sure it doesnt mean much... but at least they know I think they suck!
The people on the phone tried to help... but didn't really know how to go about getting someone to talk to me about bootloaders... they even recommended me checking out XDA to unlock it... LOL awesome.
I told them that I am perfectly fine with voiding my warranty... so can I please get this flashed to an international version... no idea how to answer something like that... oh well...

Don't see why you would think it was necessary to open a thread to say the obvious. If you don't want at&t sell it. Buy an international. C-ya bye

Yeah right. I'm sure this thread will be locked. I knew what I was getting when I bought it. I really didn't care as long as I could root.
If flashing and ROMing is that important, get a different phone. The T-Mobile version of the Note 3 is unlocked and will work on AT&T. I prefer AT&T because I get 4G/LTE where I live and in the building where I work.
Very happy with my Note 3 rooted and using Xposed, Wanam, etc. No need for a custom ROM. At least for me anyways.

AT&T has analytics on social media and Web information they collect on what is being said about them. Most large companies do and thought this might get some attention.

It should work as long as it's not carrier locked and the bands are all the same. (Buy a Google Play Edition or a international variant if possible.)

If you don't want to spend the money get a att phone on contract ...
Phones cost money, especially off contract.
Plus a used s4 is going to cost 3 to 4 hundred dollars, more if they are carrier unlocked.

getting a sprint note 4 via craigslist

What should I watch out for?
Any particular version or bootloader which is unrootable?
Im not in the US. Only getting this because it is cheap.
So can someone with knowledge on this answer me,
I would like to sim unlock it myself. And unlock all bands for all network frequency.. Including LTE.
A Samsung galaxy s6 I once had was stuck on H+ (umts/hspa) no option to put it on GSM or EDGE. And that got me uneasy because it's huge loss of battery with time.
Thank you

Use swappa.com (they at least verify that the phone isnt stolen or under contract). Prices vary but at least it is safer then Craigslist
