You didn't provide any detailed information about your phone model, firmware or even a step by step description of how you did a factory reset. So we have no way of discerning whether you missed any essential steps or narrow anything down.
Nevertheless you have an odd problem that no one else seems to be reporting. Ergo the most likely explanation is odd settings or corruption on your phone. As a factory reset (clearing user settings) apparently didn't work, the most plausible remaining cause would be a cache problem or some anomaly in your system files.
To that end, try wiping the cache from recovery mode. If that doesn't help, then use Odin to write a full stock firmware to your phone to replace the system files as well. If your problems persist then open a support ticket with your carrier to look into your account configuration. The latter is unlikely though if the SIM works in another phone. So in as much as we can tell given the paucity of details, you should try replacing your system files with Odin. Also check your APN information.

I'm on AT&T and having the exact same problem. I switched from Verizon as AT&T has a new tower in my rural area for better reception. I have 3 bars in my home and when talking on the phone it goes up to 4 bars. No problem calling out. Purchased the new Samsung Galaxy S5 on 9/15/14.
Incoming calls go directly to VM. Sometimes the phone works as it should and calls and messages came thru in a timely manner.
Mostly the calls go to VM and text messages are delayed. Vm doesn't show up as having a vm for hours.
I have gotten a new sim card, exchanged the phone and the new phone does exactly the same thing, I am now past my 14 days so I am stuck with this phone unless I agree to a warranty replacement phone from AT&T. (Same phone S5)
I have has 4 cases with AT&T and nothing has helped. Last case will be resolved bu Oct 4.
I will try turning off WIFI while at home and see if that helps.
I have reset the new phone, did not help. I don't understand why with 3 bars I can't receive calls.
Calling out is no problem. Incoming doesn't work correctly. Any suggestions are greatly appreciated. Thanks in advance.

Friends of mine were at my house over the weekend and he had a samsung s4 and had the same problem after logging onto my wifi. It is the wifi causing the problem. I had an old modem and netgear router that we hooked up and then we were able to receive calls like you should. We switched out the modem/router combo on Sat to my older setup and my phone is still working normally! I called my dsl provider and told them about the problem as I just bought the modem/router combo from them recently.
They never heard of anything like this. I do find it hard to believe that the home wifi equipment disrutes the cell phone signal. But my phone is now working!!! Anyone ever heard of this or that can explain why this would happen I would love to hear about it.

No data after having WiFi enabled for a while

Hello,
I've had this issue across more than 1 device and more than 1 carrier.
Here's what happens:
I enable WiFi, and for a while everything works as expected. I can send and receive MMS messages. I can disable WiFi and go back to my 4G connection.
The problem is, after an unknown amount of time, the phone drops the 4G connection in the background. I only know when I can't receive/send MMS messages anymore. At that point, if I disable WiFI there's no 4G data connection, and I have to turn Airplane mode off and turn it back on.
This is really annoying. It happened to me using Sprint and a Galaxy S4 (both stock and custom ROMs) and it's happening to me with a Galaxy S5 from MetroPCS. (I've used the stock Metro ROMs, Stock T-mobile ROMs, and Custom T-mobile ROMs).
Right now I'm using a Stock T-mobile ROM with the latest firmware, carrier is MetroPCS.
What can I do so this doesn't happen? It's really frustrating.
Thank you for your time.

Disabled "Smart Network Switch" in WiFi Settings?

Disabled "Smart Network Switch" in WiFi Settings?

Hello.
That's already disabled.
Should I enable it?

I tried with "smart network switch" enabled and disabled and problem still happened.

My S5 G900F Android 5.00 (Smart Network Switch disabled, Power Save disabled) on EE UK has had this problem for 9 months after phone upgraded itself to Lollipop (EE win the accolade to being the SLOWEST ON THE PLANET to provide Android updates.....). Since Jan 3, my wife's G901, a couple of weeks after it upgraded from 5.0 to 5.02, has developed the same problem. Neither phone has ever been rooted or other.
I have fruitlessly searched everywhere for a solution without success. EE Customer Services Tier 2 & Samsung's own service centre have failed to fix it. EE & Samsung blame each other for 5.1 or 5.1.1 not being available for download. Neither is prepared to resolve the issue despite hours on the phone. Have tried Safe Mode, Factory Reset, clearing everything, reloading APNs & Samsung even reloaded Android. All a waste of time: Many many days of it!
After approx half an hour connected to Wi-Fi, only way to get the mobile data to connect, is either reboot, enter & exit Air-plane mode or flip the 4G > 3G > 4G connection under More Networks. Have tested the fault in different cell areas countries and continents; fault is same everywhere.
It seems there are quite a few sufferers of this problem.

Samsung S5 keeps losing data connection
I have the same problem. My new Samsung phone loses the data connection (even though data is turned on) and I can only re-connect by restarting the phone. The first EE shop I took it to couldn't help at all. The second gave me a new SIM - that didn't work. Then I tried online support and after 3.5 hours of my life, in which I was passed on from one person to another, they completed a factory re-set - which didn't work (and additionally lost all the personalisation of my screen and some of my contacts). So I now have a not-very-smart phone which I have to re-start every time I want to use data. This is a business contract and the phone is less than two months old, but I'm not getting any effective support from EE. Android version is 5.0.2

me too, since last update. and app 'phono' shows "mobile data off" not got a time on it, but when i leave wifi coverage, it wont reconnect to cell data 2g/3g/4g. flightmode toggle to restore.

Abandon hope if you have this intermittent mobile data problem!
...at least until there is a software update, though I have no idea if that will help.
I have now tried a new sim card, a factory reset, and a replacement phone - which was provided only because I'm a business customer and I found a sympathetic member of staff. *By the way, I was told that if you are personal customer they won't consider replacing your phone if it is more than a month old - even if you started complaining about the phone as soon as you got it, the chances are a month will have elapsed by the time they put you through the hoops of a new sim, reset etc - and then it is too late to insist on a replacement phone.
In any case the replacement phone didn't resolve the issue so I have reached* a dead end. My phone fails to connect to data after having been connected to wifi - you have to do it manually each time you move away from a wifi connnection. At first I was doing it by restarting the phone, but am now following the advice of someone else who has the same problem and am going into flight mode and out again. *
This is not satisfactory, and it seems from reading forums that EE are to blame for the problem rather than Samsung, but I'm not 100% sure about that.*

Possible solution that works, for me, at the moment!
Having suffered this issue of my S5 (SM-G901F) not connecting to mobile data after being on Wi-Fi for a while unless switching airplane mode on/off for a few weeks; although it has probably been happening since the update I received late December; I have tried all of the turn this switch off, factory resets (x2), etc, etc, etc. and Googled the issue without success.
I have found this thread interesting, and I even tried calling EE support only to be told "you have tried everything that we would tell you to do" and "it wouldn't be a sim card, or handset issue, sounds like software". The reply was basically that like-it or lump it until the 5.1 update is released "by Samsung not EE because EE do not release Android updates". [Perhaps EE don't release the updates, but the stock rom is tested by them and their bloatware added before they eventually release it!!!]
Following my last reset I tried selectively re-installing the apps I used incase that was causing the issue. No Luck!
One last thing I tried was to look at every system 'thing' that I could find which used/switched any part of the mobile/mobile data/wifi - in addition to the settings I had already tried (all of which were mentioned in this thread previously). One thing I could not find not mentioned here, or anywhere, was the VoWi-Fi call on/off which I had always set to on as I do not live in a great reception area. Calling over Wi-Fi is great when you don't have a strong mobile signal.
Having 'played' with this setting for the last 24 hours I have found that the VoWi-Fi on/off appears to be a possible cure - for me anyway.:fingers-crossed:
When VoWi-Fi was set to off and leaving the phone connected to Wi-Fi overnight, the S5 immediately switched to mobile data this morning when I turned the Wi-Fi off . It continued to switch between Wi-Fi and mobile data all morning whilst out and about in and out of Wi-Fi connections - Woop Woop!!!
I then tried switching VoWi-Fi on (with Wi-Fi on and at home), leaving the phone for a number of hours, only to find that when I turned Wi-Fi off the phone refused to connect to mobile data even with a 'decent' mobile signal. The only way to get it to connect was to go back to switching Airplane mode on/off.
Switched VoWi-Fi off again, left Wi-Fi connected, left the phone for a couple of hours, etc. and hey-presto immediately switched to mobile data when I turned the Wi-Fi off. [Dances around the room because he's got the S5 automatically switching to mobile data again. Even though I'm at home with a great fibre internet and strong Wi-Fi connection!!!]
I do not know if this could be a solution for the others who are suffering from this issue, but it appears to be a solution for me at the moment. I thought I would share as your previous posts have helped me and you all seem to be pulling your hair out; like I have been; trying to find a solution.
Try it, it may work, but don't shoot me if it doesn't!

It's encouraging to know that I'm not crazy. I've had this issue across two devices and carries.
John,
Thank for your suggestion about WiFi calling. Unfortunately, I always have it off! I never used it, so maybe I should try turning it on? We'll see lol.
At this point, I think this is going to be my last Galaxy line phone.

Is it wi-fi calling that's causing the problem?
I have wondered if there is a link with wi-fi calling, but haven't tested it properly. I signed up with ee and bought the Galaxy phone specifically so that I could use wifi calling, as the town where I live (in the Scottish Borders) doesn't get a mobile signal strong to work reliably indoors from any of the networks. I'll try turning off wi-fi calling to see if that sorts the data thing (though I see that for one person above it did not). That would mean I wouldn't get calls or texts when I'm at home so it would not be a permanent solution for me. But in fact the wi-fi calling is not reliable anyway....

Brian,
You never know the way things are going with this issue; given that nobody seems to be able to pinpoint the fault; turning it on may just sort it!!!

still no change and its a pita.....

G935V on Android N 7.0 issues with receiving calls/texts [Total Wireless]

I have been going through a weird issue on Total Wireless. When I use Android 6.0.1 and below, I have no issues with my service at all, everything works as it should. The issue comes into play when I use any Android 7.0 ROM, be it official or custom. Outgoing calls/4G data are fine, but I cannot receive any phone calls or send/receive texts. The only way for me to be able to receive calls and send/receive texts is to dial out once. After this, everything works as it should, that is until I reboot. Then I it goes back to the partial working state until I dial out again.
The issue persists whether I am using CDMA/LTE or Global Network modes. I have tried every single possible combination of starting with a fully working 6.0.1 firmware and upgrading through Smartswitch, with and without a full Wipe performed afterwards, doing a full 7.0 firmware flash. The issue is always present, and I am not sure if TW has issues with Android 7.0 or if there is a problem with my account. Their CS is absolutely useless in helping me with the issue, and our chats always end with if I can make a phone call, then the issue is resolved. They don't understand that the issue is still present, but it only crops up after a reboot of my device.
I have tried 3 different SIM cards and they have deleted and re-added/reprovisioned my device/number to their system but nothing seems to help this issue. APN is the usual TRACFONE.VZWENTP. It's really weird that it happens on two separate devices that I activate with my mobile number.
My only thought as to what it could be is maybe some weird provisioning error with the number coming from Verizon. Total Wireless doesn't have any type of VOLTE capabilities on their network, yet I was able to use a rooted Note 4 device and activate Advanced Calling/HD Voice and I believe Wifi calling as well and use it fine on their service. One oddity I noticed is that when the phone is in the initial 'Searching for Service' state on a fresh boot when I dial out while connected to Wifi, sometimes I will see Mobile Network Type change to IWLAN, whereas it usually says LTE. After dialing everything works correctly.
Any ideas on further troubleshooting steps I can take? If nothing can be done, maybe there is some way I can have a boot up script that makes a ghost phone call to any random number and immediately disconnects so I don't have to remember to dial out whenever I reboot my device?
Thanks

I don't have a solution yet, but you're not alone. I have a stock G935V (running Nougat) with Tracfone service running over Verizon's network. Whenever I start up the phone, the phone will indefinitely remain in a "Searching for Service" status until I initiate one phone call. Then the network instantly switches to "Verizon Wireless" and everything works correctly for as long as the phone remains on.
A long phone call with Tracfone and Verizon yielded no solution: They indicated everything is configured correctly in my account. Various replacement SIM cards didn't change anything either.
This issue happens with both stock Samsung S6 phones and the Samsung S7 phone in my household. All are running Nougat.

Any update here? My girlfriend's phone has the same issue since moving from Verizon to StraightTalk.

Tracfone tried, half-heartedly, to solve the problem by sending me 3 different sim cards. The problem never went away. I just got in the habit of initiating a call to voicemail whenever I restarted my phone.
The problem went away when I upgraded my S7 Edge to Android v8 Oreo.

I have flashed the Nougat "U" firmware on my Verizon S7 Edge. I had VoLTE, hotspot, HD voice when calling someone on Verizon (but the HD symbol doesn't show on my dialer, only on theirs).
Only issue was that. when I introduced the TW SIM, the APN was auto set for Tracfone (and it wasn't working), so I had to manually change it to the TotalWireless one.
Since then I had received the Oreo upgrade and the following security update... and it's still OK.

Wifi calling - inconsistent with 8.1 Oreo - T-Mobile

I'm finding that WiFi calling stops working randomly. A reboot gets it to work properly again. I have my advanced call settings on Global and Wifi Preferred as my option.
Anyone else having this issue with Oreo 8.1 and T-Mobile?

I've had this issue since I upgraded to 8.1. I've been planning on doing a factory reset to see if it fixes the problem, but I really don't want to go through the hassle of setting everything up again.
I have no cell signal at my desk at work, so I use the WiFi calling often. However, I have noticed something rather strange. If I try to make a call or send a text, it will sometimes say something like "No WiFi network available". There have been a few times after it has done this that I have received a call on WiFi, and then it will work fine for a while. Otherwise, a restart fixes it.

Another thing that I noticed is that when on Wi-Fi calling, sometimes the phone will only ring once before a call goes to voicemail. Seems like there may be a delay in the call coming through. I generally have a good Wi-Fi connection, but like any Wi-Fi connection, it can come in and out occasionally.
I want to avoid a factory data reset as well.

I have the same problem Essential on Sprint

I am also experiencing this since the 8.1 upgrade, 8n T-mobile. Multiple networks that had WiFi calling pre-update are no longer functioning on either of our phones(wife and I both have them). I often work in a basement, so this is an important function for me.

S10+ Internet Connectivity Issue After Updating to One UI 2.0

So my s10+ (G975-F) was working just fine. After updating it to latest update, it has been acting really weird. The internet would stop working all of a sudden, like messages on messenger would not send, snapchat would not load, same with fac3bpok and chrome.
Anyone else facing thiis issue? Any help would be appreciated.

your mobile signal really poor.... one bar only...
wifi signal also 2 bar only, but... are you sure your wifi connection also running good ?

I have similar issue: No mobile data connection since updating to Android 10 on 12/31/2019. WiFi is working fine. Tried wiping the cache partition as suggested above. Tried restarting, resetting network. Tried calling carrier (Redpocket/Verizon) who did provisioning and taking out SIM card and reinserting/restarting. When switching SIM card to another phone (Galaxy S8+ using Android 9), no issue (Internet worked just fine). But another SIM card on my cell phone (Note 10+) didn't work either. So clearly the issue is with my phone (after the software update), not carrier. Took the phone to local Samsung store on 1/2/2020. Was told I was the first one reporting this since the Android rollout. They suggested factory reset which I am very hesitate to do. Then they suggested waiting for a patch to be released, if there will be one ever.
I am using Samsung Note 10+. I am in California.
Any advice? Thanks
