Have anyone tried to activate razr verizon devices on other network? Both USA carriers and 3rd party (EU, Latin, etc) Never found this information in the internet
The only other carrier I have tried is Google Fi. And it worked perfectly fine. No issues. After I pay off the device, I will be switching from Verizon to Google Fi.
My unlocked xt2000-1 works on FI, although call are very unready, the phone desmt ring, nor I am able to place calls reliability. Data and txt msgs work great. I have tried to activate it on tmob, but have had no success, for some reason, tmob cant activate it.

[Q] How do I use my Vibrant for gps and wifi while avoiding roaming related charges when in Canada or another country?
[A] this is the question I asked support at t-mobile. I got 2 answers, neither were completely correct. The problem is that you cannot block IMs and phone calls from reaching your mobile unless you go into airplane mode. (Note that you will receive charges for IMs and for calls you do not pick up as long as they register on your phone. This is what I was told by one rep. Other reo said that I should not be able to receive these since my account was not set up for international services, but as msgs and calls came in, I got worried.)
The short of it is this: for $20, I bought CoPilot off the android market and downloaded the North America maps. This app does not require data connection, and it works remarkably well. I then put the phone into air plane mode. After doing this, I enabled gps and wifi. This allowed me block all direct calls and IMs while retaining the ability the ability to use the phone for gps and for browsing when there was an available wifi network. (having a google voice account actual enabled me to send IMs when connected to a wifi network.)
It all worked so well, I am further considering dropping my data plan altogether since the places I typically use the internet are places with wifi (though perhaps I will wait until the 2.2 update is pushed.)

In terms of GPS, you are correct, you would have to purchase a third party GPS app for that (since google maps doesn't cache. Well it does, but if you find yourself lost after choosing a route and don't have wifi available then you are forced to turn on data so it can redownload your route, since it only caches your route and nearby streets.) To block incoming phone calls you just set up unconditional call forwarding (**21*18056377243# send) which will forward all of your calls to VoiceMail. The 1805 number can be replaced with your VM provider of choice (ie Google voice.) To undo, just dial ##21# and send. After that just disable data roaming and you are good.
In terms of stopping IM/SMS/MMS, just have care add message blocking (or better yet, go to your tmobile account and add it from there) its a free service that blocks all incoming or outgoing sms/mms/email as sms/IM. Sometimes the reps will just add the sms/mms block so you might want to add it yourself from the site.
Also if you purchased the vibrant on a contract then you can't remove your data.

Or if you want to keep the FULL functionality of your phone while traveling internationally you could buy a prepaid SIM for a carrier in the country you're visiting.

this ^^
If you did not want to get a SIM, you could just take your t-mo sim out. This way you could still use wifi, then use Google voice for texts and VM.
If I purchase an unlocked phone (lets say Motorola Atrix) from Amazon and don't purchase a SIM from any provider, will the phone work over wi-fi?
In other words, if I am traveling overseas, and use the free wi-fi at a hotel etc., can I get emails and make phone calls over wi-fi and skype or do I need a SIM for the phone to work?
Thanks
yes. wifi works regardless of the SIM card. That is how I used my atrix (with an old SIM that didn't have service) until I got it unlocked
You can use GrooveIP to make phone calls over wifi via Google Voice (no sim). I can confirm it works on the Atrix.
I have an Atrix 4G that I purchased in the US. Voice and Data worked fine in the US. Now I live in Macedonia, and voice works fine, but I can't get Internet to work. When I put my Macedonian sim card into my old HTC G1, it works fine. I've been to 5 mobile reps to confirm that my APN settings are right.
Any ideas out there what might be going wrong?
Is it possible that my unlock code worked for voice but not internet data?
Perhaps a radio flash might help.
According to the specification sheet, my Le Max 2 (Model X820) has all the bands required for Verizon. I am always interested in finding out whether it can be used on Verizon network, and if so, how. I have done quite a bit of experiments and would like to share my findings.
First thing first, and I am sure most of us know it - you cannot activate a Verizon SIM using this phone. It must be an activated Verizon SIM that you pop into this phone.
I am using an Xfinity Mobile SIM, which uses Verizon. It is not a Verizon prepaid or post-paid SIM. I do not think it makes any difference in my experiment though.
I can get one of the two working conditions: (1) 3G voice + 3G data, or (2) 4G data but no voice. In case (1), the phone is connected to Verizon’s EvDo network. Voice works fine. Data also works, but it is only 3G. In a phone call, data is disconnected, which is what an EvDo network does. In case (2), LTE data works, but Voice is out of service. I did try VoLTE but to no luck (The same SIM works fine with VoLTE in a Nexus 6P).
To me, only case (1) is a workable solution. When one would like to think in case (2), we can supplement Verizon’s LTE data with voice from another SIM. It does not work. When LTE data is set to use Verizon, the other SIM does not work at all. Some people may be fine with Hangouts or a VoIP solution though.
For a dual-SIM set up, it goes like this: SIM 1 – Verizon, for voice/SMS, SIM 2 – ATT or T-Mobile, for data. The drawback is that when you are in a call, data is disconnected.
But even for such a set up to work, there is some work to be done. Based on my limited knowledge of how Verizon’s CDMA network works, it seems that for voice to work, some provisioning must be done (information such as MDN, PRL, etc.). I find that this provisioning is only doable in a Chinese stock ROM. Once that is done, use TWRP to make a copy of the EFS partition. That is my savior. With such a “provisioned” EFS, it is possible to use Verizon in custom ROMs such as RR or lineage. If this EFS partition is overwritten, then the phone will not work with Verizon in case (1).
I know in the past, people have used software such as CDMA workshop, or Qualcomm’s programming software to set parameters for CDMA network. I do not know if it will work for this phone or not. But that is clearly beyond my skill level.
How do you get 3g voice and 3g data work?
Heyyo, tbh I made a build of LineageOS 15.1 with some kanged verizon files from Sagit (Xiaomi Mi6) but of course I can't test it as I am in Canada... if you're willing to try it out and report your testing it would be appreciated.
LineageOS 15.1 test build with Verizon files:

This is the change:
https://github.com/TheMuppets/proprietary_vendor_leeco/pull/25
I cannot test it since I am not on lineage. Op mentioned he can get 3g voice and 3g data. I would wonder how to get those since I only get 4g data.

Sorry for a late response.
For 3G voice and data to work, I chose to force 3G in settings. I used the RR ROM. Settings --> More --> Cellular networks --> Preferred network type: Choose 3G instead of LTE.
You can also use the dialer, enter *#*#4626#*#*, then Phone information. You can choose network mode there too.
So I got the phone and it's working really well. My biggest issue is the lack of VoWifi. I called T-Mobile and the tech felt it should have it.
When I dialed *#*#4636#*#* (I think it's that), VoWifi is greyed out. Is there any way to use ADB or anything to force-enable it? There's no way, with the LTE/5G bands it has that it cannot be enabled on T-Mobile...

It can be related to your provider or it's SIM settings. I use Dual SIM. My Vodafone (NL) in SIM bay 1 has the WiFi-calling option. My KPN (NL) in bay 2 doesn't have it.

You will only get wifi calling on Google fi on xperia 1, xperia 1 ii and xperia 1 iii. I have used all three phones on tmobile and it doesnt get wifi calling but on Google fi they do.

That's because Google has its own WiFi calling implementation, not using VoWIFI. It should work on just about any device.
I am able to get VoWIFI on T-Mobile after flashing Sony's Developer Binary (for the Xperia 1 ii), but unfortunately that one comes with some other unacceptable compromises (like no task switcher). Anyway the attached screenshot shows the service screen (dial *#*#INFO#*#*) on T-Mobile with this firmware. T-Mobile WiFi calling also works with even more out-of-fashion phones like my Nokia 9 PureView, so I would say this is definitely a Sony firmware issue.
In turn, the WiFi hotspot function does not work on Google Fi on any of my Xperias (1 ii, 5 ii, 1 iii). The client (e.g. laptop) connects to the phone and gets an IP address, but can never reach any website. It works fine with other phones (Nokia, Samsung,. ... and even the same developer image), and it works fine also with the Xperia on T-Mobile and AT&T. I suspect some iptables/firewall incompatibility between Fi and Sony's stock firmware.
I returned my phone back to sony because of missing vowifi.
T-mobile expert said its fully compatible but Sony expert said All Sony Phone dont have vowifi (disabled by software)
So I bought Xperia 1 III (along with a prepaid 3HK SIM card) when I was traveling in Hong Kong.
I inserted that 3HK SIM card to Sony phone, the Wi-Fi Calling was an option in the setting menu.
But after I returned to US, I swapped an Ultra Mobile SIM card to the Xperia 1 III, the Wi-Fi calling option is gone.
Before that, the Ultra Mobile SIM card worked perfectly on a Samsung Note 9 (also Hong Kong version) with Wi-Fi calling enabled. So it looks like it's a software problem.
Tried Google Fi SIM card, I was able to activate Wi-Fi Calling in Google Fi app, but not in phone setting menu.
T-Mobile VoWiFi is incompatible with the stock Sony firmware. You can get it back by flashing one of Sony's developer binaries onto your OEM partition (for "open devices" like the Xperia 1 ii and 5 ii but not 1 iii); however this also makes the phone not really suitable for day-to-day use (for instance, no "recent apps" switcher).
FWIW, T-Mobile VoWiFi works great on my older Nokia 9 PureView, which is definitely not a "known" device as far as T-Mobile is concerned. So the issue is limited to the combination of T-Mobile USA and stock Sony firmware. (Of course, VoWiFi also does not work on AT&T, but that's expected since they only provision AT&T-branded phones).
WiFi calling works on Google Fi, because they use their own implementation (not VoWiFi). Alas, WiFi hotspot functionality is broken on Fi - there seems to be something like a firewall/iptables incompatibilty between Fi and the Sony firrmware. The client (e.g. laptop) is able to obtain an IP address and ping the phone, but is not able to then connect to the Internet. (This, too, is fixed with the developer image above).
FWIW, as a workaround, you can install the T-Mobile DIGITS application and enable this feature on your account to make calls over WiFi. The only caveat, as I learned today, is that this does not let you make international calls. :-(

They are actually just meant to bring back some of the original Sony functionality (e.g. camera) on top of a plain-vanilla AOSP build. For instance you can build and install AOSP 12 and then flash this image to the OEM partition. Won't give you Google Play services though, so not really useful for most people.
However you can also flash it on a stock Sony firmware. (Just apply step 7 in the AOSP instructions above, without doing the rest). Fixes some issues, including VoWIFI on T-Mobile and WiFi hotspot on Google Fi, but unfortunately the recent apps switcher is then gone.
Only available for "Open Devices" like the Xperia 1 ii and 5 ii, but not 1 iii.
I know this is a roundabout solution, but it worked for me:
Port your number(s) to Google Voice. This will end your current wireless subscription.
Sign up for a new wireless plan, with new numbers. (*) If you order a new plan online, it's a good idea to do this first so that the SIMs arrive ready for activation before you start the previous step.
Set up Google Voice to forward your calls to that number. Or better yet, install the Voice app on your phone - you can redirect both inbound and outbound calls via this app/service. (I.e. you can use the native dialer to make Voice calls; however for text messages and voicemail you need to use the Voice app).
Optional: In the native phone app, block all inbound calls directly to the new number (remember, your primary one is now on Google Voice).
This also gives you the ability to send/receive calls, voicemail, text messages on a web browser. In other words, all of this is essentially a roundabout way of getting functionality similar to Google Fi; but remember, Fi's hotspot does not work on the Xperia.
(*) Apparently if your carrier is T-Mobile, cancelling 3+ lines and then signing up for 3+ new ones won't give you the same discount as the original signup. According to a local T-Mobile store rep I talked to, if you cancel and recreate service within 90 days, the system thinks you are trying to somehow cheat on discounts. Weird -- I ended up going (back) to AT&T for this reason. You may also consider T-Mobile MVNOs such as Mint Mobile. (**)
(**) Oddly enough, in addition to better overall coverage, I get much higher download speeds on AT&T LTE/LTE+ compared to T-Mobile 5G (NR/NSA) - even in a place with full bars on both carriers. I did a test today with two SIMs in the phone - on AT&T I got 100 Mbps down on first try, whereas on T-Mobile the best I ever got (20+ tries) was ~30 Mbps down; typically 15-20. Not sure if this is another artifact of the Sony firmware, YMMV.

Course, if you only need to make domestic calls while on WiFi, T-Mobile DIGITS is the path of least resitance.
