Thunderbolt to New Cricket 4G LTE

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

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.

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.

VZW to ditch CDMA.

Do you ever see a day when VZW will ditch CDMA and start using GSM? I hate not being able to use my phone with another carrier. I also don't see any real advantages to CDMA. Any thoughts or opinions on if you see this happening?

Verizon will switch from CDMA to GSM, probably never. CDMA is very well suited for covering long distances with a minimal number of towers. Therefore, CDMA is the best platform for countries with large land masses. CDMA is more secure, and the phones are more energy efficient. Also, CDMA phones produce far less EMI.
If you really need the international roaming, there are Verizon phones with global capabilities. Or switch to T-Mobile or AT&T, and deal with that headache.

I would love to see verizon ditch CDMA for GSM! Its a pain to have accumulated phones that I will not be able to use once I switch to a GSM provider. The problem is that it doesn't seem like there is any incentive for Verizon to WANT to switch from CDMA

CDMA is better than gsm in some ways and gsm is better than CDMA in some ways I prefer cdma

Verizon already has been rolling out LTE, is it not just a matter of time before they start to put all services onto that? I would think that at some point Verizon just won't need CDMA anymore.

LTE is based on GSM technology. On current Verizon LTE phones, CDMA is used for voice and texting (and data when there's no LTE), but data (when there is LTE) goes over LTE. That's why you guys have SIM cards in your CDMA devices.
What verizon is planning to do is abandon CDMA for completely LTE phones in the future. What this means is voice, texting, and data will go over LTE, similar to VoIP. It's called VoLTE, which means Voice over LTE.

It's actually at a lower frequency than their CDMA bands. 700mhz band. Lower frequency has better wall penetration. Frequency has nothing to do with bandwidth either.

GSM doesn't just mean SIM card. LTE uses GSM protocols. Sprint is the same as CSpire; no SIM card slot. However there's a chip that emulates a SIM card inside the phone. It's probably the same case for CSpire users. The HTC One on Sprint has a SIM card slot though. So does the iPhone 5.

Well, if a phone supports LTE, it doesn't necessarily mean it can do GSM. For example, the HTC Rezound and most newer phones on Verizon do GSM, but only because the phone happens to support it because the chipset is designed for global roaming. But the Galaxy Nexus on Verizon, for example, doesn't do GSM even though it can do LTE.
There was a guy who took the Photon Q on Sprint (the Motorola slider), unsoldered the chip that pretends to be a SIM card, and soldered on a SIM card reader. He was able to use normal SIM cards in his Photon Q afterwards.

don't some CMDA phones have sims though?

Those are phones that also had a separate GSM radio in them for traveling abroad (like the DROID 2 or even the Touch Pro 2, which were not LTE phones).

Ahh, ok. nice to know. Going to attempt to get my D3 on USA ATT this weekend. I hope it works as I really don't want to shell out money for a new phone. I like my D3

There going to leave CDMA eventually but not for GSM. There is a new form of LTE they will eventually adopt because its backwards compatable with the original LTE . Than they can pull all of there cdma and older lte equipment along with the 1x stuff that has been phased out and removed as it dies.
I dont see all of this happening for another 4-5years for the full switchover though and its posable they may leave cdma in some markets to help coverage as it seems some areas LTE just eats it.

Fix for T-Mobile LTE?

Is there a workaround or any suggestions to get everything functional such as calls etc.
As of now only data works but you can't receive or send out messages,make calls etc.
When connected to H+ everything works flawlessly and the carrier shows, when connected to LTE only data works nothing else and the phone can't identify what carrier is being used.

UPDATE:
The issue seems to be that Verizon by default is locking the GSM radio. Users are reporting the same in the Moto X and Droid Ultra forum. Users using 4.4.2 on T-Mobile with a Verizon device.

AFAIK, LTE (unless the carrier is using voLTE) is a data only network. Verizon uses LTE for data and CDMA for calls and text.
Verizon seems to only allow GSM/UMTS or CDMA/LTE on the M8 at one time, there doesn't seem to be a true Global mode that allows GSM/UMTS and LTE to run at the same time.
That would explain why people are reporting either LTE or calls/texting (which, as above mentioned, only works on 2G/3G (be that CDMA or GSM))
The question is, is there a way to get around this? On the S3/S4 there was an app called phoneinfo which showed more modes than the Mobile Network settings menu. Is there such a thing for the M8?
This is quite disappointing news for me, since this is the first Verizon phone I'm aware of that has the 1800MHz LTE band, and that's the band used in Australia where I'm headed soon. I was excited about being able to finally use LTE there! I guess I'll have a choice between LTE and calls/text like all those in this thread using T-Mobile.

More than likely it is same as Verizon. Won't happen till they have voice and data both over AWS network. Currently on Verizon data is on LTE and voice is on CDMA. If can get into signal settings may be a way to lock the voice section in. It is not on LTE. Verizon has had the two linked since TBolt. Others have had a problem doing this. Has to be able to do dual band at same time. Also shouldn't get LTE at all if not in T-Mobile AWS area.

Unless T-Mobile rolls out voLTE and the M8 is compatible, the VZW M8 won't work for both call/sms and LTE data simultaneously. The other solution would be figuring out a new mode that allows LTE and GSM/UMTS to work together, maybe a software update will do that, but something tells me VZW isn't running to make our lives easier in this regard (Unless they start offering international 4G LTE roaming, then they'll have to fix this issue - and that might be on the horizon as this is the first VZW phone to have LTE bands that VZW doesn't use nor has any plans to use, such band 3 1800MHz)

T-Mobile has to certify and allow the phone to work on band 12 or else it won't be able to make 911 calls. They've verified the US S7 but I don't think they verified the international version.

Hi there !
I belive that WIFI calling and the reduced Internet speed while on a phone call, are the two things that are different on the Exynos. Tell me how to check and make sure WiFi doea not work and I will try for you. I have tested the second one, and indeed the Internet speed is way reduced when talking on phone. Depending where you are, it is either H+ or 3G.

i believe there should be a setting for wifi calling within the "more connection settings". if it's not showing within the settings, then it's not supported.
as for band 12, how reliable is that app you used? a lot of people have mentioned that band 12 is not supported on the exynos model, so i'm really curious how yours has it.
thanks!

OK, there is no WiFi calling setting under there.
As for how reliable the App is, I have no idea, sorry. I searched and found it was mentioned in XDA for checking this kind of settings/capabilities. I will take a screen capture of it once I am in a building and it is showing the band used. My understanding is that LTE Band 12 is particularly good and improves signal inside buildings.

The Internattional version does support band 12. and it works, however for VoLTE you have to find a firmware that has it which is hard. the Czech t-mobile firmware has VoLTE but no WiFi calling

The "F" international version also has Band 17 for AT&T

why do people who DON'T have the phone act like they know what they are talking about.
Works fine on T-Mo, and ATT. you just miss out on some of the bands, and also carrier features like VoLTE.
my 930F works fine on Tmo. and it'll work fine on ATT as well.

Carrier compatibility in US?

Hello,
It appears based on the bands (best I can tell) the global mi mix 3 may have a chance of working on Verizon? Is that a true statement or to much to hope for?
What other US carriers will it work with?
Thanks!

Hello,
It appears based on the bands (best I can tell) the global mi mix 3 may have a chance of working on Verizon? Is that a true statement or to much to hope for?
What other US carriers will it work with?
Thanks!

T-Mobile/Metropcs (2, 4, *5,12, *46, 66, 71, *252, *255) and likely AT&T (2, 4, 5, 12, 17, 29, 30). The doesn't have ALL of those, just listing their respective bands.
Also, Xiaomi will hold a taster event in December (NYC). Mix 3 will probably be there.

I have both a Google fi and an att Sim card in mine. Keep in mind the mnvo part of Google fi doesn't switch carriers so it's perpetually on T-Mobile. Sprint does work. Popped in a friend's Sprint Sim card just to test.

Yes. I have att in mine works perfectly. Have project fi coming next week. Good to know that works as well.

Have you tried using "Signal Info" app for MNVO part of google fi? It has a setting to tell it to do the auto switching, not sure if this will engage some setting for the phone or not. Thought I'd check. If not at least you could maybe test the carriers, sprint, US Cell, & Tmobile .

Installed the Signal Info app (not Signal Spy). Will let you know if it switches to Sprint. I work in a building that has horrible T-Mobile coverage so I have to revert to either wifi or my AT&T sim.
FYI: It allowed me to enable the auto switching code (*#*#342886#*#*) but not carrier specific codes (e.g., Sprint)

So will it auto switch for Google Fi? I'm in the same boat as you I have ATT for work but Fi for personal.

Does not auto switch unfortunately. So it's stuck on T-Mobile. Not a big deal.

Does WiFi Calling work on T-Mobile?

Are you able to send SMS/msms messages from you Fi sim? If so how did you do it?

Anyone try on Sprint or Verizon yet?

I send via Hangouts app for SMS and MMS

Not sure if it works. It doesn't indicate WiFi calling. Airplane mode with WiFi turned on does not allow and calls unless it's thru the Hangouts app.

I installed VoEnabler module and while it gicesw the option to turn it on in settings doesn't seem to be working in real world testing.

I would like to pose a genreal qustion about sprint's B41. It would seem to me that if the 8G/256G phone receives B41, that this phone would receive it, correct? Unless sprint has done something funky with the B41 spectrum, of course.

It should if the part of the band 41 spectrum is in line with what Sprint uses. Some spectrum blocks use slightly different frequencies. If the Sprint merger with T-Mobile goes through though, Sprint's CDMA will mostly be be eliminated after about a year after the merger completes. T-Mobile did this when they originally bought Metro PCS as well. For longterm use, I would be more concerned with the lack of band 66 and 71 as well as a few other missing T-Mobile bands.

Mix 3 256G/8G has: 1,2,3,4,5,7,8,12,13,17,18,19,20,25,26,28,29,30,34,38,39,40,41,66 bands
I guess time will tell if B41 will ever work with this phone. Sprint uses FDD (or something) that might be a funky version of their own standard.

Ahhh., I get the bands mixed up between the Mi Mix 3 and Honor Magic 2. That was why I stayed away from the Magic 2, was the lack of US bands.

Was it you that said that they updated to the Dev rom and Fi works with it? I thought I read someone said it did.

I'm using Dev rom w fi and att Sims. Hangouts and Hangouts dialer as my defaults

Ya, you know, Sprint is going to be tricky to test because Sprint locks their phones. From what I understand, taking a sims out of a Sprint phone and putting it into another does not work because Sprint wants the IMEI from the phone. That is why no one would want to use Sprint or would be desperate to use them. I was just wondering if Big John got a hold of the assets if he would continue the funky thing with the B41 or what it would turn into. It would be intersting to know because B41 has a 7 mile out reach, maybe further. Anyone else has a take on this?
