[Q] can the droid ultra be flashed to cricket?

Title is the question.. I can not find anything about this on the internet.

I would have to say "no" on that one since it's tied to Verizon's CDMA network and they use a different set of frequencies than Cricket does which is tied to Sprint's network. The Ultra/MAXX/Mini are already factory unlocked for GSM purposes, however, so that does offer a lot more choice in terms of carriers overall, but still no chance of use with Cricket.

So then i can use this phone for the No Annual Service Contracts, for sprint? It is a verizon phone but it could be unlocked for sprint.
nice well thanks buddy

Sprint uses frequencies that aren't compatible with the Ultra/MAXX/Mini so now, you won't be able to use any of those devices with Sprint - that's what I just said. If you can't use it with Sprint, you can't use it with Cricket, Boost, etc. They're not compatible devices, and flashing wouldn't change that.

Thanks for your reply
So Will the Ultra work on T-Mobile then? or does it only work on Verizon. The IMEI is clean, and I just want to know what i have to do to use on any other network but Verizon.. I hate Verizon..

It's as simple as what I just explained: there are two primary cellular technologies, CDMA and GSM. CDMA traditionally has never required SIM cards in their devices and is used by companies like Sprint, Verizon, Boost, Cricket (in the US) and many other cellular carriers worldwide. GSM has always required SIM cards and that's used by AT&T, T-Mobile, Straight Talk, Simple Mobile, and many other carriers in the US as well as around the world.
The Droid Ultra, the Droid MAXX, and the Droid Mini are all Verizon contracted devices but because Verizon must now provide unlocked GSM capability in the phones they sell (at least for the Droid series, that much I know for sure, but other devices like Galaxy S-series, iPhones, I cannot be 100% certain about) that means when you get a Verizon branded device you should be able to - and you can with the Ultra/MAXX/Mini - put a GSM-based SIM card in the phone and use it with any GSM-based cellular carrier anywhere in the world without having to pay anyone to "unlock" the phone for such use.
tl;dr version: Yes, you can use the Ultra with T-Mobile, you just need a T-Mobile SIM card with active service on it and you're good to go. I used my recent Droid MAXX and the Droid Mini I had with T-Mobile without any issues.
But I got sick of waiting around for a miracle that probably won't happen so I sold both of them, got a Samsung Galaxy Express last night, 20 minutes after I got home I had unlocked it for T-Mobile (using the well known unlock trick), rooted it, installed CM11 Official on it and it's been working fantastic today and pulling down close to 35Mbps with T-Mobile's LTE here in Las Vegas.
I'm a happy camper at the moment...

[Completed] Switch to AT&T from T-Mobile

Hello and thanks in advance, my question is- I'm going to change to AT&T service from T Mobile service and I want to make sure that all my t-mobile branded phones would work properly on AT&T service.
My phones:
(all network unlocked and t-mobile branded)
LG 90
Iphone 5c
Samsung Note 4
-Would my phones celluar and data networks work on the att network?
-Would my tmobile phones get new updated firmware and software when it's released if used on ATT?
-Would MMS and imessage work?
-Would visual voicemail work?
-Should I just buy ATT branded phones? I don't really want to as I have expensive phones already and would be super expensive to get all new ones.
-Is there anything else I should know before transferring service?
Any suggestions or info is appreciated.

Hi, thanks for using XDA Assist!
Your best bet would be to call AT&T or go to a store and speak with a representative.
Good luck!

LG Urbane 2nd Edition LTE. Help getting ATT version working on T-Mobile network

I managed to snag an Urbane 2nd edition LTE before they cancelled the launch and pulled them from stores. At this point they will have to pry it from my cold, dead hands if they want it back (unless it blows up on my wrist). I want to put this device on the T-Mobile network. Has anyone had luck getting it to work on the t-mobile network? If so, what steps did you take. I have a t-mo nano sim card with smartwatch service installed in the watch, but I am not getting t-mo service. I was on tech support with t-mo for two hours and they were unable to get it working. Any help would be appreciated.

Trouble provisioning
The issue isn't the watch itself but an issue with T-Mobile not being able to tell that it is an actual wearable. Too many people took advantage of the wearable plan on a regular phone so they had to lock it down to only tmobile branded devices. I have been using my iPad sim to get just data for the watch, which is really all I wanted anyway. Don't want to be that guy talking to people from his wrist.

Adding it as regular device?
Do you think I could add it as a regular phone and have it work? I would not get the $5 smartwatch plan, but it would only cost me $10. I can afford and extra 5 dollars a month if it works.

No the watch is not locked to ATT. They wanted you to think that though

It's not locked. I am using it on Canadian Telus network

Watch is not locked. Using it with a Truephone sim (Truephone uses ATT network). Works great.

You know there is a recall on this device right?

Not locked
I see some of you say is not locked.
Does that mean it's open to all carriers?
I live in Europe and I'm dying to get the watch, but as I could understand it was only working on 2 carriers in the States.
I've found some watches on eBay, and I'm kinda willing to pay what ever the price of it works over here in Europe.

Yes, the ATT version (only one you will find on Ebay or anywhere) is not sim locked.
The Verizon (other carrier) version, which never ended up being sold after all, would probably not have a sim card slot, since Verizon is not a GSM carrier.
Bands ATT posted were: 850/1900 GSM (2G), 850/1900/2100 UMTS (3G) and 850/1900 LTE. I'll be able to test it in Europe soon and see if it has any unpublicized bands and thus may work over there. Will post findings in here.
I had mine up on Ebay, then changed my mind and decided to keep it for now. Even without a sim card in it, I can use its GPS and track my runs without a phone.

@xendula did you ever try a phone plan with the watch? I'm having the same problem as in your OP, and am at the point of switching plans.
Otherwise, I may just switch providers...

I believe if you add the watch as a phone, instead of a wearable, it does work on T-Mobile if that's what you're asking. I've had my AT&T version watch since last November and I'm using a Truphone SIM with no problems. I also used it while visiting family in France and had no problems there either.

Yes you can add it as a regular phone and it will work. I decided that I did not need to use it as a phone and decided to deactivate the SIM.

jaydoggy is correct, I have an AT&T Urbane 2 on the T-Mobile network. I added it as an extra line (unlimited talk/text 2GB data for $10 per month).
There are some owners who have gotten the ATT Urbane 2 to work on T-Mobile with the $5 wearable program. It takes a call from a T-Mobile store Employee to their engineering support level. I tried at 2 local T-Mobile stores but each time the employee couldn't get the support engineer to code the LG watch as a Gear S2 which is supported by T-Mobile on wearable plans.
Try the $5 route, but know that it will work with the $10 add a phone line option.

AT&T Gear S2 on other carriers possible?

I got an att gear s2 but I don't have att service so I wanted to know if I can use it to connect to let's say T-Mobile since its an esim.

Unfortunately this is why American carriers, at least that's what my knowledge covers, f&#king suck! Out comes this new technology that for the first time will allow people to have the potential to use any carrier with the same hardware, and then carriers like AT&T refuse to unlock them.
Yes, I called AT&T and T-Mobile and AT&T doesn't unlock watches. I hope someone finds a way to somehow port the T-Mobile software over to the AT&T hardware.

The esim should be universal right? Like it should work for any carriers. If so wouldn't it work if we pay for an unlock code? Even tho we wouldn't be inserting another sim, the imei would be released to be used by other carriers. Does it make sense at all? Lol
My n6 was like that. It couldn't be used by other carrier until I unlocked it and its imei was released from att to be used by others.

The problem I noticed is the fact that there are custom settings for AT&T and so even if you unlocked it, I think you would need to still flash the appropriate software. I'm just guessing though.
It's really frustrating that I've got the first big consumer device using an eSIM and I can't take advantage of it's most basic and essential feature.

Any updates on this? The AT&T watch is like half the price as T-mo and I'm interested in using AT&T watch on T-mobile if possible

Any updates? I just switched mobile carriers from ATT to TMobile and would like to use my watch on their network

I have the S2 Classic SM-R735AZKAATT (for AT&T obviously) but I'd like to have it set up with T-Mobile.
Can I take this into T-Mobile and set up service? If so, anyone know how much?

Unlocked Note 10 + - Unable to flash T-Mobile Firmware

I wish I would have known that WiFi calling wasn't supported on unlocked Note 10 + before purchase. I need WiFi calling and so I am trying to flash the T-Mobile firmware onto my Unlocked Note 10 +. The problem is that I am not getting any of the T-Mobile branding or features after flashing. I think this is because it doesn't recognize my SIM as being a T-Mobile SIM. I use Mint Mobile which is a MVNO running off the T-Mobile network. If I would have just kept my Google Pixel I would have all the features that I need that T-Mobile offers such as the WiFi calling and HD voice.
Is there any way for force the device to enable the T-Mobile specific features available in the firmware? I am thinking about going and pickup a prepaid T-Mobile SIM to see if it will activate the features with that. I am beyond frustrated at this point as I have an expensive phone that I can't get any of the features on that I had on my Pixel 2 XL.
Any help is greatly appreciated.

I have an unlocked Note10+ (N975U1) with T-Mobile (standard unlimited-everything plan), and WiFi calling works fine for me with the default unlocked firmware.
You may be right about the sim card. If T-Mobile is your carrier, can you get a regular sim card from them?

I don't know the answer to your question, but can tell you of a similar experience I had buying an unlocked Note 8 from Samsung and trying to use it on Verizon network. No WiFi calling, visual voicemail and other notification features, in spite of hours spent on phone with Samsung and Verizon. I ended up returning it and buying the Verizon branded one. Lesson learned! There are cons as well as pros with unlocked phones.

It depends on the carrier. T-Mobile is good about supporting its features on unlocked Notes, definitely including WiFi calling. Verizon is not.

WiFi calling does appear to be working now on the unlocked firmware for me. I have the latest update that was just pushed a few days ago.
