WiFi Calling Option Missing From Settings With Metro by T-Mobile. - Huawei P30 Pro Questions & Answers

Hey all. I'm missing my wifi calling option completely from my phone. I found that before, I was missing my E911 number from my provider (Metro by T-Mobile. So I had them change the E911 address to my current address, and I also had them do a network refresh. I restarted the phone, and the option is still completely missing. Does anyone have any suggestions on what else I should do? Thank you.

Rogers Phone [unlocked], FIDO SIM, always Roaming...

Hi everyone. I have been doing a tonne of reading trying to figure out a couple of things for my Treo 750.
It is a Rogers phone for which I paid an online service provider to unlock. I am using my FIDO SIM in it without any problems.
It says I am always roaming and although assurances from FIDO I won't be charged Roaming fees, it gets kind of annoying everytime I check my email that it tells me I am roaming and asks if I am sure I want to do this....
So, I understand there is carrier specific info in the carrier.pxp file. I am told the Rogers network code is in this file.
Am I able to edit this to include the FIDO network code 302370 so the phone doesn't think it is always roaming?
Would it be better to unbrand / unlock the phone to WM6.1 via the methods I see here in the forums? [dubLeE's method].
Thanks everyone,
Ryan
It has nothing to do with your phone. It's the fact you are using the Fido GSM card on a Rogers network. It has nothing to do with whether your phone is locked or unlocked, and changing the carrier code won't do anything.
To disable the roaming network check when you check email, from Outlook Mobile go to Tools -> Options, choose the email account you've setup, then go to Send/Receive Schedule -> Advanced Settings -> check "Use automatic send / receive schedule when roaming"
Hi number16. Thanks for the reply.
The "Use automatic send / receive schedule when roaming" doesn't seem to prevent the "You are currently roaming. Synchronizing may result in additional charges" dialog box when the schedule is set to manual. In fact, the checkbox is greyed out and not selectable with a manual schedule. Even with an automated schedule configured, you are still prompted when doing a manual send/receive.
I was thinking that if the phone was configured such that it thought its' home network carrier code was the FIDO code, it wouldn't consider me roaming.
Anyways, sounds like I am stuck with it. Thanks again for the info
I have the exact same problem with my work Exchange email on a Rogers Touch Diamond. The roaming has to be defined by the ROM or registry. When I put my Fido SIM in a Rogers Samsung Jack flashed with the Fido ROM, there is no issue with roaming.
Hi there,
Same issue here, I am using my unlocked Treo 750 from Rogers on Bell network.
It works fine, except for the roaming issue.
How to get rid of that triangle icon on the top?
Were you able to edit the carrierDB.pxp file?
Please help.
Did you change your network settings over to the correct settings for the network of the SIM card you are using?
Unlocking a phone will allow other SIM cards to work, but if you don't change your network settings, then the phone will still try to connect to the Rogers network.
How do i unlock the network, i have a samsung corby phone which is rogers based and am using a fido sim card. Everything works except the internet which comes up as network error. please let me know if you can help. email- [email protected], thank you.

This is a Palm Treo 750 forum. You should find a forum specific to your handset for exact instructions.
In general, your phone probably has a 'Settings' menu which would have some sort of option to edit your network settings. That's where you would make the change. You would have to get the proper settings from Fido.

If I have the APN set to the one for the network of the SIM Card I am using then will I not get charged roaming?
Is it possible for it to actually be roaming and me not knowing about it?

Cannot enable "Mobile network" after upgrade to latest FW

Hello,
i've just upgraded to the latest official OTA FW 3.08.405.3
Sense3.0 is great, but i cannot turn on mobile network anymore - i tried it both via Quick settings and Wireless settings menus - it cannot be enabled. And even worts is that it doesn't report any error msg and the 3G sign doesn't appear on status bar. There is noting in the log too...
Does anyone has the same problem?
I just wrote a mail to HTC support, but don't know if they track this as support channel...
This is terrible - i can't live without mobile network connection ...please help!

This might sound weird, but is there anything in APN setting?
Try to mess with the toggles. I have had similar problem. I constantly turned airplane mode on/off and switched from GSM to WCDMA. Finally it goes, if this isn't related to apn. Hope i helped.
10x a lot guys !
it didn't recover APN settings after upgrade
I previously checked them, and assumed that check-box is selected, but actually it was not. It should be colored in green, but actually it was in grey
Unable to re-enable Mobile Network for data-only SIM Japan -- possible bug?
Having a similar problem, some more details:
PHONE:
I am using an unlocked (but unrooted) Incredible S from Virgin Mobile Canada with a data-only BMobile SIM in Japan (runs on DoCoMo's network apparently). Android 2.3.3 (Virgin Canada circa August 2011).
PROBLEM:
Mobile Network intermittently gets disabled and cannot be re-enabled normally. APN is fine, SIM card (phone number) is still detected. Toggling Airplane Mode or Wireless Network does not work, Select Automatically returns "unable to connect, try again later", Search Networks and choosing DoCoMo returns "Your SIM card does not allow a connection to this network".
SOLUTION:
Only reproducible solution is to remove data-only SIM, insert voice&data SIM (from my SoftBank phone), now Mobile Network is available so re-enable it, power down and replace data-only SIM. Once restarted Mobile Network automatically enables. Obviously this is not a convenient fix.
Once was fixed by randomly hitting network settings in frustration, but I have not been able to reproduce this solution.
OBSERVATION:
When on wireless, Mobile Network is also greyed out. When Wireless Network is disabled, Mobile Network automatically enables properly (for the most part, at least once I suspect it did not).
Thus I feel like it's a bug, either in OS or DoCoMo's network, but BMobile and HTC both point the finger at each other and have no useful suggestions for me.
ASIDE:
I hear Android 2.3.5 is available for Incredible S, perhaps this fixes the problem. However, this update has not appeared in my updater -- is it possible that because I'm unlocked I've lost access to the update server?
Thanks in advance for any suggestions.
mobile network disconnected
Have also the same problem, tried all the above suggestions but none works. Phone only shows limited service but with x on the signal bar. BUt when i try to tap the sim tool kit, it displays "SIM toolkit not ready or unsupported".
Hope somebody here can help me. Thanks

T-Mobile WiFi Calling "Data service is blocked"

I just ported my number from Verizon to T-Mobile and they don't have service at my house (neither did Verizon). I'm trying to activate WiFi calling but I frequently get the message "Data service is blocked" from "Phone Services". I'm on latest Pure Nexus but I'm not sure if ROM has anything to do with it. I called T-Mobile and they did a network refresh but the issue is still persisting. Wondering if anyone else came across this and what fixed it?
This is from the PN thread:
ProBird79 said:
I have figured out the WIFI calling problem. If you delete the "T-Mobile IMS" APN it will neuter your WIFI calling. This APN isn't selected and I wasn't aware that you needed it since the standard "fast.t-mobile.com" APN is selected. I'm not sure if this is only within this ROM or widespread. Also, I'm wondering if this is the reason VoLTE hasn't been working. I don't have anyone to call at the moment to test this out but I will report back once I find out.
This was hard to find as it changes after a reboot and not instantaneously. So even though I didn't change anything I rebooted then the problem persisted.
Edit: Also, you must have to use the phone app within the ROM and not the Google Phone app or WIFI calling seems to break.
Edit #2: This was also the reason VoLTE wasn't working. All is good now!

The above solution worked for me after I tweaked the APN settings from this post: https://forum.xda-developers.com/nexus-6p/help/getting-volte-wifi-calling-to-metro-pcs-t3284024 post #4
After that, the T-Mobile IMS" APN was listed and I deleted both entries for IMS. Once that was done, T-Mobile Wifi Calling was back!!

How to enable Wi-Fi Calling on the SM-N920I? Option appears to be missing

I am on a fully updated Note5 SM-N920I, finally just got the service back up and running after switching it from ATT to T-Mobile. The T-Mobile supports Wi-Fi calling, as they texted me a link to fill out the E911 address, and then they checked compatibility and said it was compatible. But I don't see the Wi-Fi Calling option toggle button anywhere. I checked in Settings > Connections > More Connection Settings ; and I also checked the samsung Phone dialer app > Settings and did not find it anywhere. Is this because it is the international version SM-N920I? It's not a deal breaker, but it would be useful to have, since the signal inside is between -88 and -99 dBm, so sometimes it can get spotty and drop. I'm just glad to have a signal again (ATT was literally blocking / un-provisioning all Note5 models except their own locked ATT version SM-N920A, the bastards; I spent two weeks troubleshooting the problem and had to solve it on my own; in the end I simply ported over to T-Mobile). Anyways, if you know how to find the Wi-Fi Calling option on the SM-N920I, I would greatly appreciate it. My assumption at this point is that it was removed from options on the international versions like mine, since the feature is dependent on the carrier. But maybe it can be found in a hidden setting page somewhere? Again, I don't absolutely need this, but it would be great to have. Thank you.

Question Data not connecting on ATT since "3G switchoff"

So on Monday ATT decided to deactivate my sim card because they believe my phone is incompatible with their network now. All my bars went to 0 with an x on it and I couldn't do anything on the phone. I went to an ATT store, got them to give me a new activated sim and I put it in my phone and all my bars came back.
My phone says VoLTE again too by the signal bar area. I also tested a text and it went through fine. I received a phone call and while it works fine, it sounds like junk now. Like it is no longer actually using VoLTE like it always has. My phone doesnt seem to have any data however, when it should have LTE just fine. I also cannot make any calls, even though it says VoLTE on the phone, it just re-routes to ATT customer service instead of going through with the call.
When I go into the network area in settings it says no IP address either. I looked and my APN is set to nxtgenphone, Preferred Network Type selected on LTE. Before ATT deactivated my sim card LTE has always worked fine, and LTE should still work fine. It is only the 3G network being shut down. Also given the fact I have the VoLTE icon the phone is apparently connecting somewhat to an LTE network.
So does anyone know how to fix settings to get data working again? Is it just an APN that needs to change? What is everyone else doing with the network shutdown and has anyone else had issues like this?
I had the exact same issue, your issue is in fact APN settings I'm having them as well. Try deleting your current APN and putting in a new one. Once I got a new sim my APN reset I could call but no data and no text. I have half of the APN information in place and have data and basic text, but once I input the MMS port the APN data disappears still trying to figure that out. Not sure if anything I typed is helpful but at least you know your not alone with a mi11 on ATT and it can work

Thanks for the reply. I tried deleting the MMS port and also the proxy just now and data didnt come back. I will try searching around for more APN info for how phones are supposed to connect now and see if I can find anything.
It looks like from what I could find that it is due to an IMEI whitelist ATT has, blocking data connection on any device not in their whitelist. The solution seems to be to root the phone and change your IMEI to a whitelisted model.
While my phone is rooted my IMEI is not cloned I definitely would not share my IMEI with ATT. When I got my sim card yesterday I had the attendant activate but I did not provide my phone so he did not get the IMEI from my phone. If you got a sim and they input your IMEI that could be a problem possibly. Just a suggestion to try and get a sim activated at a store without your phone.
I had also heard that most ATT MVNOs were not having the device whitelist forced on them yet, so I went and tried 2 different ones yesterday. Both failed to get the phone working on their network with their sims.
Before I went through the hassle of rooting (and most likely losing payments) I tried ATT again anyway. I used their online customer service chat and the first person I chatted with said he could help me with the lte data problem and the IMEI issue. I was skeptical, but he actually did fix it all up. He just needed my sim ICCID and my phones IMEI1 and he submitted the info to their backend people for adding to their system. It took almost an hour and a half for it to get added, but overall it was a pretty painless process and I was browing the web most of the time while waiting in chat. I now have LTE data again, VoLTE again, and "5G" too (which ATT 5G is really just one or two more features than normal LTE and is no faster in speed and uses LTE data bands). I attached a screenshot showing the data and VoLTE working on my phone. The first signal is ATT, the second is TMobile (which has always worked and never had an issue, their 3G network shutdown is going on for another 4-5 months)

Happy you are back up and running and I'm glad that you found someone at ATT to do the fairly easy work of getting your IMEI cleared. Lots of people have been worried about devices not working on ATT because of this whitelist issue glad to see there are workarounds just wish ATT didn't make it so convoluted.
