I'm almost positive that you should be able to pop in any sim card, pre- or post-paid, and it should work...

i just tested it with a nextel chip with a plan but no data service and i still get no bars??? i will try to put up some pics....please help if ya can...thanks

As far as I know Nextel doesn't use GSM networks it has it's own iDEN network, I don't know what the difference is, or if it should work with a GSM receiver but I can't say I'm surprised it doesn't work. Also from what I've heard, the phone has only received FCC certifications on T-Mob and AT&T for the phone you have, Verizon passed separately. Again, don't know if this helps, but I'm not shocked it doesn't work. Your phone is carrier unlocked, it came that way from HTC and unlocking the bootloader has nothing to do with which carriers it will work with.

no all i did was i bought it on a tmobile network through google then i had unlock the bootloader then rooted the phone now is there a way to use differ carriers??? i did not buy it unlocked......from google.....so is there a way ?

Dude... your question is moot! The phone, even if bought on a T-mobile line, IS NOT LOCKED TO ANY SPECIFIC CARRIER! You can pop in ANY GSM SIM CARD, and it will work. I bought mine on a T-mobile upgrade... but I can throw in an AT&T, Rogers, Fido, Vodaphone, etc., SIM, and it will work just fine.

o okay will try it out with att thanks...

Can D3 and activate on pageplus?? and where can i get the phone with no contract?

Can D3 and activate on pageplus?? and where can i get the phone with no contract?
i think verizon offers $459 and amazon offers $549~ but how can i buy the phone with $459 price?

and can i return it if i cant get activated on pageplus

You need a verizon account to purchase the phone, or find a friend that does. The d3 should work on pageplus as its not a new 4glte device that requires a sim to activate, uses an old school *228 activation

what does that mean??

If I buy the phone from Amazon wireless will it be unlocked, that is, can it work anywhere in the world on any GSM provider's SIM?
A proper answer would be much appreciated.
I seriously wanna buy this phone and I am willing to pay the $550 price at Amazon wireless, if and only if, the phone is unlocked.

Someone can correct me if I'm wrong, but I don't think the D3 isn't a GSM phone. I'm pretty sure its only a global cdma

The Droid 3 is a GSM and CDMA handset, it is mentioned in the verizon manual for this handset that a sim card can be inserted, currently it is suspected however that this is sim locked.

Go to the Global Phone section in this PDF and it is mentioned

It is a global phone that supports GSM networks. Arguing over it won't help us much. What will help is an answer to which version of the phone is unlocked for all GSM networks.

Its is a GSM global phone, includes a Verizon SIM that is locked. Verizon customers in good standing can get the phone unlocked with a call to Verizon Global support.

Hmmm....yes, but the question here is whether the phones with no contract are also SIM locked or not.

hi guys, can anyone answer my question

So, here's the response I got from the Amazonwireless guys:
{I'm very sorry but the replacement phones (phone only no service) on Amazonwireless are locked to the carriers. You would need to find an unlocked phone.
There are basically two types of unlocked phones. CDMA Unlocked and GSM Unlocked.
An Unlocked CDMA phone will basically work with carriers like Verizon, Alltel, and Sprint. Unlocked GSM phones work with carriers such as AT&T and T-Mobile.
Unlocked cell phones are designed to work with any carrier that uses SIM cards. Some advanced features may not work depending on the carrier you are using. I would recommend contacting the carrier you are going to be using to ask if the phone you are interested in will work with their network, and if there are any features that you would not be able to use.
If you would like to shop for an unlocked cell phone please visit Amazon.com using the link below
www(dot)amazon(dot)com/cellphones
I hope this information helps. We look forward to seeing you again soon.}

Thomaslau it means that this phone still needs to be activated using *228 which pageplus accepts. 4gLTE phones do not use *228, they use a sim card to activate

so it will works???

What my understanding is with CDMA is that it's ALWAYS unlocked. The problem lies with carriers not allowing foreign ECID/IMEI's on their network database which allows the phones to work.

Should work flawless

ok, now i got my droid 3, but i struck at the activation menu, the one with the android robot. what should i do to activate my phone on pageplus?? do i need to activate my phone on verizon then pageplus?

I thought with pageplus you call them, give them the esn from the back of the phone, starts with a000000, then dial *228 when they tell you to

Unless I misunderstand your question, you can use either version of the S4 Active with AT&T prepaid "out of the box". You don't need to unlock anything.

a friend of mine just bought a new s4 active. she was/is on a business plan on her family account. they are no longer going to use att for service. so she is stuck with this phone. she wants to do a prepaid plan with att. is it possible to make a regular service phone a prepaid phone. if so how and someone please point me in the proper direction.

You are going to have to have ATT unlock it

Umm, why? I'm not arguing; I'm just curious, since my experience was different.
I have an "extra" i537 that I got from AT&T when we signed up (signed up 4 lines on contract and got all new Actives when I did, but am using one of my SIMS in a different phone). It was brand new out of the box and, I assume, SIM locked to AT&T. When a friend was visiting from Europe I let him use the i537 while he was here. He walked into AT&T with it, bought a pre-paid SIM of some sort, stuck it in the phone, and started using it just like that. Never had to unlock anything, or at least never told me that he did...

she tried going directly to att and they failed. so i will give it a try when i get my hands on it. thanks for the help people. any additional horror stories or advise would still be greatly appreciated.
thanks again

I just did exactly this for a customer. Just insert the go SIM. No unlock required for gophone

I have a at&t locked active I traded a guy my note 2 for. No unlocking needed for me to use my net10 sim card in it. You shouldn't have to unlock anything to use it on prepaid.

Yes exactly but I thought that was common knowledge of the use of prepaid sim services. Sorry for not specifying.

thanks for all of the help. after att would not give me the code for the phone i went online and found sim-unlock.com and paid for the code. i inserted the straight talk sim card ( its what she ended up going with.) and it didnt ask for a code. but only had 2/3g connection and was only able to make calls and text. so i inserted my verizon card and voila it asked for the code. entered the code and restarted with the new card and i now have 4g and data. thanbs for all of the help

[Q] Samsung Galaxy S4 Active SGH-i537

Hi guys,
I was wondering if anyone out there can help me? I have been trying to get this this Samsung Galaxy S4 Active Sgh-I537 to work on Verizon. It is right now with At&t. I was told by at&t that the phone is unlocked already. Actually according to at&t the S4's and up come unlocked. I keep getting the Sim Network Error. I was told by at&t that that means my sim is locked through Verizon. Anyone hear of that? I am not under contract and have not been for at least a year and this phone is not under contract either. Not sure if that is true. I paid to have this phone unlocked and the site told me they cannot generate a code for this phone and refunded me my money back. I want to get this phone working on Verizon due to the fact that I have the unlimited plan an cannot upgrade without paying high dollars for a phone. I bought this phone with the understanding that it will work with Verizon. Can anyone help me or give me suggestions on what to do? I have had this phone now for about a week and about ready to sell it on eBay if I cannot get it working. PLEASE any help would be greatly appreciated.

The i537 won't work on Verizon. Verizon is a CDMA network and this is a GSM phone. This phone will work on nearly any other network in the world except Verizon or Sprint.

Bottom line first, like the other member said, your phone is GSM based. It is IMPOSSIBLE for your GSM phone to work with Verizon because Verizon (and Sprint) use CDMA technology. (And vice versa, Verizon and Sprint phones will not work with AT&T or T-Mobile (also a GSM carrier).
Not sure HOW you bought the phone, but if someone told you that the AT&T phone would work with Verizon, they told you wrong.
You have a few options:
- You can sell the phone on eBay to someone who wants a GSM phone (if it is truly unlocked that adds value to the phone. But before advertising it as unlocked make sure it is). And use those proceeds to buy a CDMA Verizon SGS4 phone.
- You can keep the phone and switch to a GSM prepaid carrier. Straight Talk is what I use. And I am using an AT&T branded Samsung Galaxy S4 AT&T Active SGH-i537. (Because I have a Straight Talk AT&T SIM card.) With Straight Talk for $45 monthly I get unlimited talk, text, and 3GB of true 4G LTE service. That's hard to beat, IMO.
Bonus Tip: Next time, notice the difference between phones. The letters that matter are "GSM" or "CDMA." If you see a phone branded AT&T ot T-Mobile, those are GSM phones. If you see a phone branded Verizon or Sprint, those are CDMA phones. Rely on that rather than what someone tells you.
Good luck.
P.S. The carriers kind of told you right. Your phone is a GSM device, but your SIM is CDMA. The easy fix, if you are not under contract with Verizon is to get a GSM SIM, such as through Straight Talk.
If you are under contract with Verizon consider switching to Straight Talk and paying the ETF penalty. This is because the savings with Straight Talk (e.g., $70 monthly off your bill) quickly pays the ETF penalty.
Pencil out the cost of your Verizon unlimited plan. Is it worth the price you are paying, over that which you would pay with a carrier like Straight Talk? If it is, then simply get a CDMA phone. Easiest way is to get an S4 that says "Verizon" on the battery cover. :good:
---------- Post added at 09:54 PM ---------- Previous post was at 09:41 PM ----------
It should have taken a carrier 15 seconds ito tell you in plain English that you were using the incorrect phone.
If I was an AT&T CSR I would have had you flip the phone over and tell me what it says or what graphic it had on the battery cover. I believe Verizon phones say "VERIZON"
On hearing that I would have then tried to sell you an AT&T account.
Whoever sold you the phone (eBay purchase) and the carriers left you floundering on the dock like a fish out of water.

[Q] SIM lock?

Hey, I'm considering buying one off of Swappa. Most of them on there have come from T Mobile, Sprint or AT&T. I want to use this thing on Verizon. Do I have any worries about buying either of those carriers rather than direct from GPS or Motorola? I know all the hardware is the same, but wasn't sure how the SIM locking worked for those carriers.

T-Mobile and Sprint will work right out of the box. AT&T will require you to purchase a sim unlock code.
