I have had no luck getting my Vibrant to work with my T-mobile blackberry plan. Phone works, but no data.
If I get a Captivate, unlock it, will it work with T-mobile's blackberry plan for data?
I don't care if it's just 2g and not 3g, I just want data...
I was told by AT&T that it wouldn't work because the data is provisioned differently. I wanted to keep my Bold 9000 for work and the Captivate for all other times and couldn't do it. I'll have to assume that T-Mobile also provisions their data differently.
At&t 3G runs off a completely different radio frequency so an at&t phone wont work on T-Mobile 3g. It will work with 2g and data provisions have nothing to do with it. Still a GSM network. Just get your unlock code for your sim and switch away

An unlocked Captivate will work on Tmobile but you will only get Edge for data.
There is a big draw back as these phone were never design with anythin less than 3G in mind. When ever I was using data (edge) all my voice call went straith to voice mail with no indications of any missed calls.
With Wifi it's fine. Even peoples with AT&T 3G have these problems when they travel to an area with only 2G coverage. Even a person in India told me the same thing with his Galaxy S.
Yeah with edge you cannot talk and use data at the same time. That's why when you're using data it will not allow calls to go through until the data stops transferring.

How come Sprint doesn't use a sim for their LTE? Is the sim even necessary or is to bring global usage to the Verizon version?

The SIM card is used for 4g. 3g and voice is over the cdma radio. And sprints does have a SIM if I'm not mistaken it's internal tho and cannot be accessed.
The biggest problem with the "non-removeable" sim setup that Sprint uses is you can't just pop it out & stick it in another phone.
I do this all the time with my VZ sim card.

thats for sprint? it looks like verizon its all handled through the sim for both lte and 3g.... right?
As far as I know its just the lte that needs the SIM. Now of course the phones are made to not function w/o them but I'm pretty sure it's only the 4g that actually relies on it
From what I've read, you can pop a Verizon 4G sim into pretty much any unlocked LTE capable device and have it work.
Now I'm guessing this is going to be a no, but...
I got an Airtel 3G Data card (specifically the Huawei E1731) when I went to India and unlocked it, if I remember correctly it kept swapping from CDMA and GSM signals. Now if I pop the Nano SIM I got with my iPhone 5 into this data card, (I'll try to make my self a Nano SIM to SIM adapter) is there any chance of it working?
I've also heard if things like the 4G sim being deactivated when you swap to a 3G device. But wouldn't putting it in a 3G device be the same as using the iPhone 5 with LTE turned off?
And is there any chance of Verizon messing with my data plan if I put the sim in the data card and start using it with my laptop?
I just saw a a video of someone putting a nano sim in an iPhone 4s and it working so I think this should at least work on the data card, still worried about the Verizon side of this.
Also I just remembered something about different frequencies, would the fact that the data card is from India affect my ability to use it?
Actually, I'm pretty sure Verizon SIM cards are only for their devices. I don't think they work otherwise

I've read from a few different reliable sources, don't have any links on hand. But its the phone that is locked to a carrier, not the sim that is locked to the phone, so as long as the device is unlocked and has the required hardware, it should work with that sim.
In verizons case, at the very least the LTE should work with an LTE device, I'm not sure about voice, 3G, and 2G.
In that case you wouldn't get 3G on other phones, since the SIM cards Verizon has are for 4G LTE only, their 3G networks are CDMA and thus built into the phone.
LTE is a GSM technology which is the only reason they use SIM cards at all

That is what I was thinking, but the data card seems to have both CDMA and GSM bands and when I pop out the LTE sim from my phone I lose all signal not just LTE.
Now what I'm thinking is that, since the SIM holds all the Account info, etc, not just 4G related things, that if I pop it into the 3G data card, (I've seen Iphone 5 SIM be put into a 4s and work) that it should work. That is if the Data card is compatible, which I'm not 100% sure on.
The SIM in a GSM phone holds all the account information. The SIM in a CDMA phone is for data only - the phone will work for voice/text without it. The SIMs are different software/wise.

That's what I initially thought but, If that's true than why is my iPhone 5 not able to use Data, voice, or text without the SIM inserted?
I'm not to worried about it not working, the thing I'm concerned about is verizon messing up my plans if I try using the sim in a data card.
There's is now 4G coverage in the Houston area.My thunderbolt is already fully flash 3G and stable. Want to enable 4G on this phone. Cricket says requires sim card to work. The only sim cards are with the new LG and Samsung S3 by cricket. I know this is possible by using a unlocked 4G cdma LTE phone with sim slot. Does anyone have a unlocked phone on 4G cricket successfully working!!!

This is in the wrong thread. Verizon 4g will only work with Verizon. Verizon owns the entire 700mhz band that 4g functions off. This makes it so no other network can use Verizon's 4g

I dont think this is true as verizon can still lease their spectrum to other carriers like Straight Talk to piggy back off their network. The biggest problem for him is going to get a non-approved 4g device on verizons network. Verizon does not want people taking flagship devices to other discount carriers. Networks like Cricket dont actually own any spectrum, they just lease it from the bigger carriers at a discount. But verizon only allows a select group of ESN's to connect to it, usually for crappier phones. Some people will go so far as to clone their ESN to get it to work, but that requires special tools developed for your phone and can be quite tricky.

Well its pretty obvious that Verizon isn't leasing any part of their lte spectrum since there isn't one single optional carrier that a Verizon 4g phone will work with.

Is it possible to unlock all GSM bands to but used with Cricket 4G LTE service?
A possible NV Edit is probably all that is required
If I installed any other Sim Card Tmobile for example you get sim card unknown error and no signal
This is being done on other Verizon 4G LTE phones where people doing NV SEEM edits and unlocking all GSM bands. Using with prepaid carriers like Simple Mobile

So far no one has managed to do this on the thunderbolt. Its not like other 4g phones and is the only one with svdo enabled.

Can the bands the radio receives be changed by software? Isn't the radio physically limited to a range of frequencies?
Sent from my ThunderBolt using Tapatalk 2
I was pretty sure that the radio was locked in to stay at the 700mhz spectrum that Verizon owns. I wouldn't be the least but surprised if it were locked in using hardware as well.

If memory serves, Cricket's LTE is courtesy of Verizon, I read it I think on Engadget a while back... Either way, it goes along with Verizon's Rural Coverage Plan to work with regional carriers to bring LTE to places where people would never expect it.
T-Mo works with AT&T phones because both are 1800Mhz or whatever for EDGE, so I would think if Sprint LTE is 700Mhz....

I doubt Sprint is using 700 they are probably using spectrum they got from the nextel acquisition (not looking stupid now lol). And of Sprint was using 700 and the had an lte roaming agreement, which they don't, with Verizon..... sprint lte phones would be working in allot more places, which they aren't.

If the info from the above article is correct you can see Sprint lte is not compatible with Verizon or ATT. In my searching I also found that apple made 3 different variants of the iPhone 5 with different lte frequency combinations.

those other Verizon 4g Lte phones, like the moto Bionic, have radios and antenna that support those GSM frequencies, and the engineering software tools to perform those tasks have been leaked.
Afaik, but I haven't looked in a while, after making those seem edits it unlocks Gsm/Edge for Att, T-Mobile and global roaming. I think it also enables hspa for Att but not T-Mobile due to frequencies the bionic's radio supports or doesn't support. It does not enable Lte for any other carrier.
its my understanding that the radio chips and antennas in the TB only support Cdma/Evdo and VZW's upper 700mhz block LTE
It also doesnt help that ril for the thunderbolt is closed source because of the svdo capabilities in it.

Anyone try getting/buying a sim card from cricket?
You would need a SIM for the phone to work at all, right, since it is needed for 3G and 1X on Verizon?

The sim would be needed for 4g to work. Cricket will provide you with a sim but you will still only get 3g because they can't get Verizon's 4g signal.

I think to use the phone with cricket you will have to have the sim but still won't be able to use 4g.

If you don't mind, I was hoping you might be able to tell me how you flashed your thunderbolt to Cricket. I have tried many times unsuccessfully, and to be honest I'm absolutely stuck. I'd appreciate any and all help I can find. Thank you so much Have a wonderful day!

I have a straight talk S3 (Verizon based) and a cricket sim card. How do I make the cricket sim work in the phone?

You need a CDMA SIM from any CDMA carrier and it will work as soon as you put it in, then you set your APNs to Tracfone APNs.
If your Cricket SIM is a GSM SIM then it won't work, it MUST be a CDMA SIM.
Verizon CDMA LTE SIMs are only $3-5 on eBay. I'm sure you can afford the price and the wait while it is mailed to you.

I used a friend's Verizon Galaxy SIII at one point... kind of... it took a while to detect the network each time the phone started up and it was only EDGE/2G
So, it works for phone calls and very slow data... might be okay if you're usually on wifi, but it's really better to just have a phone that is compatible with Cricket's HSPA+ 3G and 4G LTE network(s).

They are asking about the SIM because they have a straight talk s3 and that device has to use Verizon S3 ROMs and that makes the Straight Talk S3 require a SIM to have working mobile data, it won't work without the SIM. They weren't asking if they can use a Straight Talk S3 on Cricket network.
