Can you send/receive text messages over wifi? help end this debate

A guy I work with keeps arguing with me that you can't send text messages over wifi so setting my phone on wifi when at home to receive text messages and e-mails is pointless since it doesn't work.
Can someone please tell me if this is true or not?
The reason I use wifi is because my cell phone connection is crappy when at my house.

Your friend is correct.

Text messages go through your carrier's network, not your wifi network

+2, your device does NOT do this through the data connection, so even though you might have mobile data turned off, or in this case, connected to wifi. It's using the Short message service center to communicate the data, this is over the voice network effectively, NOT DATA.
Also, this is the wrong forum for this OP.

Some T-Mo phones, like the G2x, can connect to the voice network through wifi, still uses minutes though.
Google voice will let send an SMS over a data connection.

There is an App available called TextPlus that allows you to send text messages over wifi. It does not use your cell # - it sets you up with a generic address
I use it on my tablet and works very well
It is available on the marketplace

Get viber. Is easy and you can make phone calls and texts over wifi. Cheers!

Wifi/Wifi Calling/Airplane mode/MMS weirdness

Ok. This is very strange. It's happening on both of my One S phones. It's possible it only started after the OTA update.
When wifi is on and wifi calling is enabled, the airplane mode setting goes into a state where it says it's "turning off" and the on/off button is diabled.
When it's like that, I can not send MMS with Go SMS (I can send with stock messenger during that time).
If I turn wifi calling off, airplane mode goes into off and I can send MMS with Go SMS.
I know the OTA had something to do with a wifi calling fix, but I think they broke something.
It's like when wifi calling is on, it's disabling the ability for mobile data to come on to perform functions that are not done over wifi (i.e. MMS).

How do u activate WiFi calling? Sorry I'm not stealing your thread and is it true if using WiFi calling u don't use your minutes?

It's in the settings menu, I don't have the phone at the moment, but I think you have to click the dotted line under mobile network and it's in there. Yes, wifi calling is free, but you have to call them and add a free wifi calling plan to your account.
Any further discussion, I'd ask that you start your own thread.
Anyone able to confirm my findings on the issue I posted about and any thoughts as to what's going on?

I cannot exactly verify what you are experiencing, but I use GoSMS and I have always had trouble with it and wifi. But I do think it had gotten worse since the update.
In my situation when I boot the phone art home (where I have no signal and a fixed, auto wifi connection), wifi calling isn't on... Until I make a call. Then it takes about a minute to turn on and turn blue (it almost always starts out with an "invalid SIM" error). And in my situation, until wifi calling is running, my SMS is spotty. Them while it is initially on I can also send SMS. Then when it goes off again (usually if I don't make a call for about 30), at this point I cannot send SMS without a reboot.
I am running various log applications, and in reading the log enough times, I can definitely see consistent regular errors mentioning the GoSMS app. I also am pretty sure this update fixed a few things, but it also broke stole things.
You should go download a log program, and let me know of you see GoSMS errors.

That's for comfirming!
How'd the screw this up so badly? It's going to be months before they push a new firmware up to fix this.

Same here

So any work arounds to get MMS to work with Go SMS w/o turning off wifi calling?
Also, I posted on the T-Mobile forums here:
http://support.t-mobile.com/message/148722
Maybe some of you can jump in here and voice your complaints too?

I was able to get HTC to escalate to a tier 2 tech who was very vigilant with trying to reach me to discuss the issue.
After detailing exactly what's happening, he commented that he say some other reports of this issue and something about a youtube video detailing it as well. Said he'd look into it further.
The next day, he called back saying they confirmed it's a bug and it would be fixed in the next maintenance release, but had no idea when that would be.
Very happy with HTC's level of support (after the first few go arounds getting tier 1 to finally understand what I was talking about and escalate).
A T-Mobile forum rep also noted that they've reported the problem and are working on it as well.
Not much else I can do here. Hopefully there will be another software update coming in the next month or 2.

This is happening to me as well. Like you all, when I called Tmobile to ask them about it, they said both the signal fluctuating problem and the random airplane mode are known problems that HTC "is working on a fix for. I guess the pro is that this has been a pretty big phone for both HTC and Tmobile, right? So I'll be optimistic about a fix. OTOH, can I assume this isn't a problem in the ROMs?

Well I hate to disappoint, but this isn't just a HTC problem, I am on the Galaxy SIII and I am experiencing the exact same issue. I'm not sure if T-Mobile uses their own programmers to code the wifi calling and functions, and then just submits it to the manufacturer to add in or what, but there is definitely an issue here.

Maybe that's not a bad thing then. Perhaps an update to the wifi calling app is all that's needed to fix? That certainly would be a lot easier than needing new firmware.
Are you having the exact same issue?

Here is a quote off some research I've done:
It could be done technically. AFAIK all communication between MMS enabled components is done via standard TCP/IP. But in a regular provider setup the MMS store and forward server(s) (MMSC) are only reachable via the providers network. That's why you can not send and receive MMS via WiFi.
It's also the reason why you can not make a call and send/receive an MMS simultaneously when you have only 2G (GPRS/EDGE) connectivity.
Normally android will drop the GSM data connection if there is WiFi connectivity and all data will be routed through the WiFi interface, but there is one exception: The MMS traffic will still go through the mobile data connection.

So normally, if you are connected to WIFI and send an MMS, it triggers your phone to open up the data connection with your carrier just long enough to send your MMS. With TMobile, there is something in the programming that is stopping our phones from doing so. However, this seems more of a GoSMS issue now because the stock messaging apps does perform this function fine.

I'm seeing this problem as well, but the other issue with WiFi calling for me is that it doesn't do touch tone automated systems well at all. Such as voicemail. It straight up doesn't recognise my password input at all unless WiFi calling is off.

I owned the ONE S before the SIII and had the same issue -- It will record your password, you just need to type it a lot slower than normal. I would suggest setting up visual voicemail, or downloading a visual voicemail app like Youmail.

AT&T and calls over WiFi

It's my understanding after reviewing the thread that wifi calling or native WiFi calling is not possible with AT& T and this device??
Can any other AT & T users please comment on workarounds that you have found?.
I understand that you can use Skype or Hangouts dialer to make calls over WiFi if you're out of cellular service but the problem seems to be what happens when you get incoming calls or if you need calls to go to voicemail. What's your setup?
I currently have an AT & T branded device Samsung and I have native WiFi calling but I hate that I don't have any options for custom roms Etc.
Just trying to make some decisions. Thanks

You are correct. With root you can enable VoLTE with a magisk module. But it's well documented and I can personally testify, that unless a device had at&t firmware or is an iPhone you will not get VoWiFi.. it's the dumbest thing every and I wish the FCC would somehow punish at&t for it... But so goes it.. hit em where it hurts and switch to T-Mobile. No issues there.

Hangouts
If you use Hangouts calls coming in will go to voicemail. You get an email to the acct associated with your google#. Then download the voice file in the email and play. I use wifi calls a lot cause I'm on the T-Mobile 100 minute, 5 gig $30. Plan. Wife's on it also:good:

No Incoming SMS or MMS on Verizon

Hey OnePlus fam,
I just thought I would put this out as PSA for anyone on Verizon and having issues with SMS or MMS, as there is little information out there on this for our specific phones.
If you are unable to send or receive any text messages it is most like that the "CDMA-Less" feature needs to be activated.
You can call Verizon and ask them to enable "CDMA-Less" to your account.
Hope this helps

I had to get a new sim card that fixed my problem

Here are also a few links too; the first two are for a 6T but to concept still applies.

VZW information
https://opendevelopment.verizonwireless.com/faqs?s=LTE

Had the same issue.
Called Verizon and asked them to enable this device as CDMA-less.
Been working perfect since.

Same here. I inserted my Verizon sim in the international version. Data at 50Mbps, Voice, Visual Voicemail and outgoing text messages worked. If it doesn't work for you, make sure you are using slot 1. It may matter. If you have a very old sim, you might need a new one.
I called Verizon and carefully explained that incoming sms was not functional as this was a next generation phone for a world where Verizon turns off their CDMA at the end of 2019 and SMS is routed over LTE. I instructed him to make sure "CDMA-less" was available both in the billing account and the network account. After a bit of digging he found the provisioning settings. Seconds after the phone was provisioned, sms started flooding in the stock message app. Also make sure IMS Basic Visual Voicemail is on your account if VM is giving you trouble. I use VZW Message+ (Verizon Messages) for sms as I can text from a PC also and it will restore previous sms.
By definition the phone uses VOLTE so there is no setting for HD Voice in the phone. That feature is required on your Verizon account but you would have to be switching from an ancient phone not to already have that. I cannot locate any option for Wifi calling and it does not work in airplane mode. I have a google voice number which allows Wifi calling. Interestingly it errors when the phone is in airplane mode but works when cell service is on. It reports "Wifi Call" and appears to use the stock dialer when initiated from the Voice app. Somehow Voice is even more tightly integrated with the stock dialer now than just trapping and routing international calls. This is a bug of sorts as my Moto phone on 8.0 could call in airplane mode with wifi on.
Google Duo appears to be integrated in the dialer but I haven't tried with my wife's Pixel to see if I can switch to Duo while on a regular voice call.
Bootloader unlock was simple: Tap Build # 6x, Developer Options - OEM unlocking, adb reboot recovery, fastboot oem unlock [This erases the phone]
The 7 Pro is an amazing device! Truly the most amazing. I'm really excited. The phone is super super slippery and a drop magnet. It does come with a TPU case.
I'm going to sell my kid's mint 5T and upgrade him too!
BT sucks worse than the Moto phone but I think that is an Android thing as my wife's pixel as issues to with her car. Contacts not syncing and calls not going through while connected to BT. Just have to do work arounds when I have some time.
Hoping video is fixed for the wide camera. They are amazing; but then, I'm coming from a Moto phone which has the worst cameras. Sony knows what they are doing.

Sorry to wake an old thread but did not want to start a new one.
I have verizon and have cdma-less provisioning done already. Have HD voice on the account as well. SMS works fine but I can only send MMS not receive them.
Ive tried moving sim card to other slot, tried reboot, tried factory reset, tried different apps...nothing.
The only time MMS fully works is when I am in safe mode. Anyone have any ideas on what it could be?
Thank you

Try looking in permissions at what app has permissions.
Try the Verizon message plus app

Permissions were all good, sms/mms permission is in one.
I tried verizon app, MMS works, dont really like the app though, and the customization didnt help me like it enough to keep it.
Super weird that verizon messages work but not the stock app or the Mood SMS app.

I had to call Verizon 2 or 3 times for them to get it right

I downloaded a couple other SMS apps and they all work fine. So leads me to believe its just something weird with the stock app and with Mood SMS. I will switch to QKSMS for now and requested assistance from Mood SMS so they could take a look. Thanks all.

I'm going to guess MMS didn't work with that app while you were on wifi? Some apps don't know how to route MMS data properly when there both data and wifi available.

It's an option that has to be enabled on the account for Verizon customers, it's the cdma-less option. It took me a couple representatives til one of knew what I was talking about lol

I think his issue is slightly different as he can recieve sms but not mms and it varies on the app he's using.

No that I already checked. I still have not figured out why I cannot receive MMS on the stock app or on mood SMS. Mood had not replied to my email. I switched to qksms and have no issues anymore.
So ya if anyone else runs into something like I did, try different SMS apps

Yup, I learned this very quickly when I got the OnePlus 6t. Just getting them to understand that the phone was certified on VZW. Then 4 techs before one knew what to do. I think they now can address quickly even over chat.

If I get Verizon prepaid will they be able to do this? I had Verizon prepaid once in the past and customer service was much worse than regular Verizon wireless. I am pretty sure that mvnos can't do it but I'm hoping Verizon prepaid can.

I'm not sure

Yeah, there's a lot more to this than enabling CDMA-less. Before about a month ago data/sms/MMS wasn't working on Android 10 based custom roms and MMS still doesn't work unless you use Messages+.

I get both fine I just have issues with them being received after the phone goes idle for a while. My issues are small stupid crap mile messenger not closing with home button all the time and and Gboard sometimes won't type into the field I'm in

SMS Delayed and Calls go Right to Voice Mail

Using the device on T-Mobile. Sometimes I'll just get a voice mail notification - without the phone ever ringing. Tested from a desk phone, and sure enough it goes right to voice mail without ever ringing. If I make a call outbound from the Zenfone 6, it will always work. Then I'm able to receive calls for an unknown amount of time. I can reboot and get calls after the reboot, but they will eventually randomly stop.
SMS also come though delayed by hours. For instance someone sends a SMS my way at 2pm, I'll get it at about 4pm. If I send a SMS out bound, I then instantly get all the inbound ones.
Anyone know if I need to whitelist something in battery optimization? So far the Zenfone isn't really good at being a phone. - great at everything else though.

Check your apn settings I think I had to update the default to whatever BYOD APN settings are for T-mobile see if it helps you

Also had this issue on T-Mobile. If APN settings don't fix it, I'd go to Auto-start Manager in Settings > Battery > PowerMaster and allow your messaging apps to run.
For me, I'd get SMS messages only when my screen was on, and some weren't received from contacts, like it shuts the apps off after not using them.

Same here. I'm about to switch providers because of this. What rom are y'all using? I'm on LineageOS 16. @wreid23 can you post your APN settings?
Tried unoptimizing all the messaging related apps, no effect.

So I found that if I turn off WiFi calls come right through. I don't know what the fix is, but I guess that's my work around.

I've found the same to be true for me. Wi-Fi connection prevents calls from coming in. I can dial out just fine.
This is extremely strange since this phone is not even Wi-Fi calling certified and it's not even a feature. This has been my biggest issue with the phone so far because you never know if you miss a really important call.

Asus denies the phone could be the problem (despite the phone obviously being the only variable). I replied to that thread anyway, with my experience of similar lost calls on a Moto x4 with Wi-Fi calling enabled. Maybe it'll give some engineer at Asus a push in the right direction...

if any of you are rooted there is an alternative for now to enable volte and vowifi: https://forum.xda-developers.com/rog-phone-2/how-to/guide-enabling-volte-vowifi-v2-t4028073

I'm having the issue with T-Mobile 7T Pro, when I got the permanent unlock approval and switched to Mint Mobile sim is when calls went to voice mail, have you found a solution yet? Phone works fine if I use T-Mobile sim, but Mint Mobile sim in the 7T Pro is when the calls go to voice mail and text don't go out, if I put the Mint mobile sim into a Pixel XL all is fine. When I had to quit Mint Mobile becasue of this and go back to T-Mobile on prepaid again, all worked well.

The zenfone 6 is getting volte with the android 11 update so hopefully that fixes this issue
