Let me start by saying I've escalated 3 tiers of tech support through sprint directly before I landed here.
I have a s10+ and my wife has a s10. Our mobile data connection where we live isn't the best and rely heavily on wifi.
WiFi calling is somehow conflicting with sprints network. I drop calls anytime I use it as well as get a location timeout message from the wifi calling app.
I also cannot send mms via wifi, only data which worked on my note 8 and s9.
Calls drop often whether on wifi calling or mobile network. Sprint believes this to be a device issue. My daughter's LG tribute (free phone) can send mms via wifi and has zero issue with wifi calling. Multiple people on sprint community also experiencing same issues.
I have updated prl as well as profile and refreshed network settings on my side as well on carrier. I'm seeing multiple reports of other s10s having similar problems.
Just bought 2 phones that pick and chose when they want to work for a whole lot of money.
Solved! Go to Solution.
I've had the exact same experience, and was told the same. Then was told my device would have to be replaced, but was on backorder, so I would have to wait at least a week till samsung sends more phones to t-mobile. Been forced to use my sons old phone since I sent my s8+ back as part of my upgrade.
I have a nice camera and a neat organizer unless I'm on wifi the weird thing is i can go 5 miles down the road works perfectly i returned mine sticking with my s8 which works fine it all started when I got an update
There must be some major issue going on. I got an s10 regular like 2 weeks ago and everything worked fine until like 2 or 3 days ago. Service barely works and calls and data would barely work. I went to a samsung store and they couldnt figure out the issue so they replaced it for me but my new phone wants to get the carrier update also and Im worried my new one will stop working if I update. Tmobile or samsung needs to FIX ASAP!
Exactly the same issue on my S10+. Can't make any calls, send or receive texts neither can I use the data network. What's is going on Samsung?
1st.. Just for clarification, when using wifi calling it does NOT use the cellular network one iota. Your phone is using the high speed internet wifi router as your tower. Now with that being said. Many wireless routers broadcast at multiple spectrums 2.4ghz and 5ghz.
As a Network engineer for a competitor of your cell company I would ask you if the wifi on your phone works else where aka work, Friends house etc.. If it's still an issue then yes thier may be a software issue on the device/s.
Now if it works fine elsewhere then the issue very well may be with the wireless router. Simplest way is to connect to the 2.4ghz if you connect to the 5ghz automatically and test or vice versa.
If that fails, then you will need to find out 2 things from your ISP. 1) What are your download / upload speeds. If it less then 10mb download and 5mb upload if may not work. 2) Is thier any update that needs to be applied to the router. The new Galaxy s10 line has new features to handle more advanced routers.
Finally, if all else fails. Inquire with sprint about a 4g Network Extender. The physical extenders do a much better job than wifi calling software on all phones.
Hope this helps
