Can not make or receive calls from Mexico

Can not make or receive calls from Mexico and unfortunately my the official solution is to use ... the Galaxy S7 not even the S8 the S7
Unless I can find a way to make my Phone work I will have to try the Galaxy S7
What happens when somebody tries to call me most of the time they get voice mail.
When I try and call out most to the time after a few minutes the phone says Call Failed.
Now I have the RSSI at max on the phone do not think the connection is weak.
The phone always receives data emails and messages.
In Mexico the carrier is Telcel
I talked to my company and Rogers "Canadian" they both say I have the right plan and like I said calls to happen say one out of ten tries.
I tried all sorts of things to get voice calls to work every time
Went into service mode manually selected bands "some where it said try Japan my phone does not have the choice"
Tried to disable 4G
Tried to find another network but Telcel is the only choice I have.
Please somebody give me something to try ?
I do not want to use the Galaxy S7
Lose unlimited photo storage
One of the best cameras I tried
Older and slower device
Lose Android updates
Lose Google Assist
Go from 128Gig to 32Gig is painful (mind you I can use a microSD card)
Gain Samsung bloat
But the solution given if I can not find a solution is to use this device.
I really half suspect if I do go with the Galaxy S7 I will not get any improvements.
What can I try to get voice calls work in Mexico ?

Probably a dumb question but did you enable roaming?
From the home screen, swipe down the Status bar.
Tap the Settings icon.
Tap More.
Tap Cellular networks.
Tap System select.
To disable roaming, tap Home only.
To enable roaming, tap Automatic.
To permit data access while roaming, tap to enable Data roaming.
Note: When prompted Allow data roaming, tap OK.
The roaming settings are now changed.

Yes it is roaming Telcel "5 bars" and R "for roaming"
As I said data is no issue, messenger, email etc....

Did Trump already build the wall?

Have you tried to reset the network settings?

if your data is working but calls are not verify your apn is set up properly.
try using hangouts dialer and see if that call goes through, if it does then it's going to be the APN. You can copy it line for line from your s7

l want to thank everybody that contributed.
I am back home in Canada so I can no longer test.
When I go back again I think just for the kicks I will bring the Galaxy S7 just doubtful if will work but who knows.
Still will try and get the Pixel XL to work.
I can not see how it would matter, Pixel XL, Galaxy S7 or whatever if the phone supports the Network it should work.
Now I seen people using the Galaxy S7 receiving and making calls ?
Will have to try it.
On the other hand I know people making the same complaint about Telcel
I checked the difference in hardware Pixel XL / Galaxy S7 they do have a few differences in the bands they support ?
Reset network connections I did think of this but but the warning seeming pretty scary.
If the Galaxy 7 works for phone calls in Mexico for my next trip I will reset network connections. Worth a try, I read googling a few people had similar issues and this worked.
APN the phone works Data and Voice in Canada, in USA but Data only in Mexico "voice one out of 10 calls". Just not sure
Either way I like new phones and the Pixel XL is better.... Pixel XL 2 may want that too

Verizon Advanced/HD Calling on Unlocked S9+

I currently have an Unlocked Galaxy S9+ directly from Samsung running on Verizon's network.
I can't seem to find a way to enable the HD Calling/Video Calling/Advanced Calling features.
Some rumors suspected if you installed the MyVerizon app it would enable the advanced calling menu, but that didn't work.
Is there any way to enable these features?
Is there a command through ADB to enable this?
Would I need root access?
EDIT: Model Number: SM-G965U1 - Snapdragon

No way to get Video and WiFi calling to work (yet), but go to Connections, then Mobile Networks and you can turn VoLTE Calls on or off, which is HD voice. It was there by default on my unlocked S9+ on Verizon. If you don't see it, you may need to add HD calling to your Verizon plan (it's free, but you have to login to the website and add it as a feature).

Ahh, I already have VoLTE enabled. Guess I will have to wait until someone finds a way to enable those other features.
Thanks for the info!

Whatsapp and Duo appear to support video calling over WiFi

Yeah, I know that they support video calling, along with a ton of other apps, but there is a native video calling option.

They got it working on unlocked S8, using some of the APKs and CSC from the Verizon phone. See below:
https://forum.xda-developers.com/ve...to/how-to-video-wificalling-unlocked-t3615027
Or just by flashing the whole Verizon firmware on the unlocked phone (kinda defeats the purpose of getting the unlocked phone):
https://forum.xda-developers.com/ve...axy-s8-unlocked-version-wifi-calling-t3699806
So I'm hoping it's just a matter of time, as I also need the WIFI calling to work on my unlocked phone. I think that's what is needed in order to send texts over WIFI via the Verizon Message+ app, which is what I ultimately need when in poor signal areas (sending texts over WIFI, without getting a second number with Google Voice or asking people to install secondary apps like Allo/Duo). Or I could just switch to T-mobile I guess, where all these things work with the unlocked phone without the additional hassle.

Here is to hoping we can get wifi calling and native video calling working on the unlocked s9/s9+ phones for those of us on verizon.

I have the S9+ (G965U1), and I have used the included Wi-Fi Calling app.
Look for Wi-Fi Calling.

I just got my unlocked S9 what do I need to do to get everything working on VZW I mean HD Calling, and video calling etc.? I've never owned Samsung Phones, I've always had unlocked bootloader HTC phones that I could do anything I wanted with. I don't know anything about Samsung accept "Odin". I still havn't put the sim card in cause I was thinking of returning the phone.

Thanks for the hint Dudeman456! I found WiFi Calling under system apps and went to its settings and activated its permissions. Now I can send text messages over WiFi using Verizon Message+ app (and not the included Messages app or Android Messages). I still don't have WiFi calling through the default phone app on S9. I wonder if there is a different phone app that I need for that purpose (Verizon Phone app?).

Same issue as my unlocked Note 8 I got from Sammy. You can enable video calling in the *#*#4636*#*# menu. You will not be able to activate WiFi calling though unless you flash the Verizon firmware. You also will not be able to use any Verizon features such as watching NFL games (but I think that is changing and won't be a Verizon exclusive) and premium visual voicemail. Really is a deal breaker for me.

What in the world does this mean "*#*#4636*#*# menu"????

All,
This is a KNOWN issue with Verizon.
I got my S9+ on Wed 3/14 from pre-order and could not get video calling to work. Went to Verizon store on Sat 3/17 preparing to wage war with them. The Verizon tech stopped me in my tracks and said it's already known. An email sent from corporate to all verizon stores indicating the problem with video calling. It is an issue with Samsung software which they are "diligently" working to correct and will push an update soon.
Notice this.. go to either MyVerizon app or the website and login. then go to devices/manage devices...then go controls then to adjust service blocks and you will see the video calling is blocked and cannot be unblocked. Apparently this is done for "our own good" until Samsung fixes the issue.
No date from the tech on when a fix will be issued.
DONT try anything crazy to enable video calling..just be patient and wait for the fix. My S9+ is unlocked too and i was assured that video calling will be enabled once a fix is issued.

That is odd. I am using my G965U1 on Sprint and my Wi-Fi Calling app is in the regular app drawer with everything else. I did not expect it to work, since it is Sprint, but it did. The Wi-Fi Calling app was available before placing a sim card inside.

I don't think it will unblock. If you didn't buy the VZW branded phone you most likely won't get video calling. I assumed this from the start. I spent a good portion of the day speaking with a VZW 2nd level support engineer supervisor with 20 years experience. He asked is there anything else that could be done besides unblocking video calls to make me happy, because that at this time it is impossible as the phone is not a VZW phone. Look in you phone profile on their website, does a picture of your phone show up? My profile is blank, that means the phone is not in their system of phones, even though I flashed the full VZW package with bloatware and all after first a full reset. My Phone has VZW splash screen and all the advanced calling menus, in about phone it says SM-G960U, but that block cant be removed. Maybe I screwed up somewhere and alerted them by booting with a sim card in? Maybe they flagged my IMEI? I don't know but the rep said point blank they can't unblock video calling on that line, and unlocked phones are not supported.

Are you all seeing LTE+ (carrier aggregation) on your Verizon S9 devices? I'm in Vegas and my device appears to sit on B13 (700mhz) and does not hand off anywhere else.

My S9 does not show LTE or 4G. I think there are a lot of bugs still.

Yes - unlocked on Verizon.

You need the right apps for Wi-Fi calling and some in framework. I don't own a s9 but that's what you need to do to get it to work. Along with some csc edits

How do I enable wi-fi calling on sprint?

I've called both Sprint and HTC and they point the finger at each other or think I cant read the menus. They tell me to go to the Sprint store which is in another town. I've called them multiple time over the past year. The M8 and M9 could do it why cant this still current high end model do it? I really could use wifi calling as my new employer has real bad signal but good wifi. I'm open to rooting/modding, as a last effort I 'upgraded' to Oreo and I'm not thrilled with it.
There is no mention of advanced calling or wi-fi calling in any of the settings menu. I do find internet calling, but I don't think that is the same. Help is greatly appreciated.

I've just started looking into this as well. For a short time I had a Verizon branded HTC-10 and that was GSM. It showed the Advanced Calling sub menu and configuration for WiFi calling. But my Sprint CDMA version does not. It appears to be locked. I've read elsewhere that unlocking the phone will "open it up" such that WiFi calling is available. But, it's no guarantee that you'll be able to use it. You have to check with your carrier's administrator. In my case, I'm with Ting and they're an MVNO for Sprint.

No data during call after oreo update

Hello. I'm hoping that someone can help me out. I have a Verizon note 8 that i use on straight talk for the longest it never would update to oreo but then i cracked the screen and purchased another used verizon note 8 from ebay. It came to me with a cricket sim card in it. I turned it on and connected it to wifi just to check it out before i transferred anything and it immediately wanted to update so i let it and it updated to oreo. I swapped over my ST sim into the new phone and stuck the cricket sim into the old phone and it updated too. But now my problem is that I keep getting the message that data is unavailable during calls. When i check the settings it says i am on CDMA/EVEDO/GSM/WCDMA. And there is no option to edit my APN. If i click on the mobile network i have the option for LTE/3G/2G but if i choose this nothing works and i have no option to go back to the CDMA/EVEDO/GSM/WCDMA and thus have to do a factory reset. I have tried texting APN to 611611 but it states my APN is already setup. I called tech support for ST and they told me to call back from another phone which i cant do until this evening when i get off work. So i thought in the mean time i would reach out to the real pro's on here and see if anyone else has had this issue. Did i mess up by updating with the cricket SIM inserted? Or could it be that i just didnt call straight talk when i swapped phones? i just took the sim card out of one phone and stuck it in the other. I really appreciate any advice anyone may have. Oh and I've tried finding the settings for HD calling to enable them, not there.
Thanks,
Amy

I'm having this same issue with my Verizon branded note 8 that I manually updated to Oreo. I called my carried, Red Pocket and they stated that this is enabled for my account. In Oreo the hidden menus seem to be disabled and I've tried other things. I may have to see if I can go back to Nougat. The dialer hidden menu I tried was *#2683662#. On the Verizon forums, other were able to get to the menu using *#4636# and enable VoLTE but that seems to be disabled for me. I tested from my coworkers note 8 and it seems to work fine on their phone.

I reflashed CRID and the CSC but my Service Provider SW ver. still says VZW/XAA/VZW. Does anyone know how to fix this?

Has anyone figured this out? I am having this very issue and Straight Talk has no clue what I am talking about.

I found this on the Samsung website and it looks promising but nothing has changed. I was able to see that the radiobutton/checkbox for LTE Enhanced is checked.
To enable HD Calling, download Shortcut Master (Secret Codes) Lite from developer vndnguyen. You will need to find the apk as it does not appear to be in the play store any longer.
1) From the option menu located in the upper right hand corner, choose Search.
2) There is a search field at the bottom of the screen. Type lte then hit the Search key.
3) Scroll down to Mobile Networks. Choose the one that show EnhancedLteServices. Then click Launch. Then click the box to enable HD Calling.
I was also able to set the APN settings to Bearer: unspecified using Shortcut Master lite but this made no difference whatsoever.
Finally, you don't need to do a factory reset each time you go from CDMA/EVEDO/GSM/WCDMA to LTE/3G/2G (auto connect), simply search in settings for reset network and then reset the network settings and reboot.

I was able to get the SIM card trick to work for me on my Note 8 as well. I have redpocket and prior to doing the sim card trick I did not have VoLTE. Now I do. It's too bad that this is majorly inconvenient and it won't stick after a reboot, by the sounds of it. I haven't tried yet. I may just tape the sim to the back of my phone or inside my case. Also, on my Note 8 prior to this, I was seeing vzw/xaa/vzw and now it has the vzw/vzw/vzw CSC with the RP sim in. I'm hoping that there is another way to fix this but at least I have a work around.

I updated to Oreo on my verizon note 8.
I dont have any options for advanced HD Calling, Wifi calling.
When I go to ims settings it says denied.
Any ideas

Wifi Calling, Verizon Pixel 2XL, using Straight Talk AT&T Sim no option

Hey all, I've been pouring over the forums here and other places trying to find a solution to my issue. I just got a Pixel 2XL the verizon version and I'm using it on Straight Talk with an AT&T sim card. So far so good except I cannot get wifi calling. I'm pure stock, android 9/Pie, no bootloader unlocks/rooting etc. The wifi calling option does not exist in the phone app nor in the settings anywhere. Even when you search for wifi calling, it simply takes you to the network and connections section of settings but wifi calling is no where to be found. I've tried the adb command (the one that apparently used to work on Oreo but not longer does on Pie) and that didn't work (though I didn't expect it to since many people said it no longer works on Pie). I have an Unlocked Note 9 as well and its wifi calling works perfectly fine so does anyone have a way to make this work? Reception at my home is somewhat lacking and I really need wifi calling.
Thanks!

Could you attach a screenshot with the WHOLE section of "Mobile Network", found inside of "Network & Internet" in the Settings -- make sure that you click on the drop down menu next to "Advanced Calling" -- this will help make sure that wifi calling is really missing as well as might point something out that may help with a solution. Moreso, personally, because I can't even imagine what the settings menu looks like missing this...

It might be a long shot but try checking the settings in the Google phone app. There should be a place that says configure IMS calling. I have this setting here and in the network settings. If you have it that's where you can enable wifi calling.

Been there done that. I have no options for setting up IMS calling. I only have SIP options. Also, I have tried the phone dialer trick (where you dial *#*#4636#*#*) and that shows the wifi calling option as a toggle but its greyed out and cannot be enabled. I even tried an adb trick that used to work on the 1st gen pixels, but to no avail.

What happens when you enter your information here?
I'll have to initiate a chat with Straight Talk. Like you I have a Pixel 2 XL with a Straight Talk AT&T SIM. The only difference is that mine is unlocked. I just ran my phone number and the IMEI of the SIM through the linked site and it tells me my device is not compatible. Since I have a BYOP SIM and the IMEI is of the SIM itself, chances are high that the SIM needs replacing with one that includes WiFi calling support.
EDIT: According to the representative I just spoke with, there's no guarantee that changing to a newer AT&T SIM will enable the feature. The only guaranteed method according to tech support is switching to a T-Mobile SIM.

Hey thanks for the help. I tried that link as well (before I posted here; sorry I should have mentioned it) and it said my device is also not compatible. I initiated a chat with them and they told me the same; switch to T-Mobile. I am tempted to do so but the one thing holding me back is my home is already a place I get poor signal and T-mobile's coverage while much improved still isn't as good at AT&T's. I realize that having wifi calling would fix any lingering signal issues but I do manage to get 1-2 bars of 3G at my house with AT&T, I figure I won't even get that with T-Mobile. So I am weary of the switch. I'll have to consider it though. I could also wait for the full rollout of the latest google voice (since it finally is bring VOIP without the need of hangouts) and just use that number instead.

So I contacted Straight Talk and ordered a T-Mobile sim card. It'll be here in a few days. I will post my findings after it arrives. Straight talk support says wifi calling works with all T-Mobile sim cards so we will see.

Hello all,
Okay, so I finally got switched over to a T-Mobile sim card (again still with straight talk). It took a while cause I had to buy a new one (the old one I had expired; who'd have thought?). Anyways, switching to T-Mobile solved all my problems and then some. Not only do I have Wifi calling, but also HD voice, VOLTE, Tethering, and 3-4 bars of LTE (previously on AT&T, I got 1-2 bars of 3G). I realize the signal issues is merely a coverage thing but I can say with certainty that switching to a T-Mobile sim card will give you all the advanced features. I hope this helps others who might experience this problem. I've been using AT&T (in one form or another) for the better part of a decade and can now honestly say, AT&T sucks.
