Guys,
Can using android damage some sim services like data connection???
My 1st sim, already 3 weeks now still there is no data. I'm at my 2nd sim now. Yesterday morning I have data connection, but on the afternoon untill now, I am having intermittent data WHERE IN when I try the sim of my friends (same network), I have data connection, stable. (same case in android and winmo)
I'm using android on my hd2 since the 1st batch of releases but this is the 1st time this happened to me.
I know if there is a real problem with it, devs could have experienced it 1st with there sim....But I was just thinking maybe there are some isolated cases.
Everything is working except data.
Thank you..

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?

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.....
Hello,
I own a N910CQ for 1.5 years now.
Two days ago, suddenly my phone started to disconnect from the network. Neither incoming/outgoing calls nor mobile data works *seamlessly*. The network connects momentarily and disconnects not so long after.
Some non-authorized fixer said that that was a typical Note series problem and asked me if I wanted to proceed further because he had to remove the front glass to try to fix it. I did not allow him to do it so I am stuck with a working but useless Note 4 right now.
Have you ever encountered such issue and if so how did you overcome it?
Thanks in advance.

Go to settungs/back up & reset and factory reset erase everything and try diffrent sim card also.maybe software or sim card issue.
No luck.
I switched from Polish ROM to Turkish one (both 6.0.1), do you think modem files might be causing such issues?
Fixer said nothing visible seemed like the root of the problem and that if I took it to a Samsung Service they would most probably like to replace the motherboard and that would cost almost as much as a new phone.
Dear experts,
I am facing a strange problem with my meizu mx5 phone data connection.
I felt that there is a network coverage issue with my provider.
But what I noticed is if I start using data as soon as I reboot my phone the connection stays. Otherwise the data connection will lost after few seconds. Does anyone has any ideas to identify if the problem is with phone or sim?

After searching all over the internet, I have tried to resolve the issue and be able to have my data connection always on.
I did this by allowing the applications to access data in background.
Though this has worked for some time, later I am back to the same situation .
I am not really sure how to resolve this problem.

I tried my SIM on another phone and the data was working fine over there.
I put another SIM on my phone and data did not work.
So I thought the issue is with my phone.
After inserting SIM back into my phone, suddenly the data started working.
Though I feel happy that the problem is resolved. I am worried that I could not find the root cause of this problem and what fixed this problem.
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
