It's been a month or so since my phone started to have problems with mobile data connection. It's most of the time offline, even if i set mobile data on; when i try to connecto to mobile data, it takes some tries to resume connection. I've also noticed that mobile data connection goes off when making or receiving calls. I've tried several different combinations of roms and radios with no success, and now i really don't know what to do. Any suggestions?

today i flashed cyanogenmod 9 on my htc one x...im getting a bug..my mobile data not connecting after disabling data for few hours...sometimes it connects after few minutes and sometimes takes hours.
i don't think its the problem if the rom. i get that too on a stock rom and unrooted phone. if i connect to data, disconnect it after few minutes and if i try to reconnect i have to wait for about 5-10mins for 3g. sometimes annoying. so usually i just leave it connected
Is this phone supposed to seamlessly switch between wifi and mobile data connections (and vice-versa)?
Mine doesn't seem to do this. For example, if I am loading a web page using mobile (3G or LTE), then I turn on wifi, the loading ceases, and the browser gives me a connection error.
I'm not sure if this is normal or not. I would think the phone / OS would know enough to wait for and use the new connection. But it doesn't seem to do this.
Got a new Note 4 two days ago and I went to enable mobile data for the first time today and my phone almost immediately crashed and rebooted. This was an ongoing cycle until I managed to be quick enough to turn mobile data off after rebooting. Wifi works fine. With wifi AND mobile data turned on simultaneously it is fine. If I am not connected to wifi, or it is switched off and mobile data is on it crashes. I am on v5.0.1 (latest for my phone)
Any ideas? It seems like a software rather than hardware issue. I hope I don't have to try and get it fixed because it is a grey import
Okay so I did some more testing and I have been able to absolutely isolate it to the mobile data connection. Warranty it is I guess
I have an Unlocked HTC 10 that I bought directly from HTC. Sometime, when I try to send a text and I'm on Wifi, whether I have a connection to my mobile data or not, the attempt is an automatic failure, even if I try to resend. If I turn off wifi, it won't enable my data connection, even if I turn it off then back on. It forces me to toggle airplane mode on then off If I want to send a text or browse the web. Also, to make things worse, the issue is completely random. I have no idea that it has happened until I try to send a text. TBH, I'm not even sure if wifi is part of the problem, like maybe it is disconnecting from Mobile Data regardless. If it matters, my carrier is T-Mobile.
Keep in mind, I have wifi calling disabled because it was more trouble than it was worth. But for some reason, the phone won't switch to data without my intervention. If I go out of range of the wifi, it will switch, but not all of the time.
Like right now, under my connection settings, Mobile Data says "Disconnected" even though it is turned on. When I just toggled Airplane Mode like I stated above, the connection was established immediately.
Why is the phone not connecting to the Mobile Network automatically? It seems like common sense when it comes to smart phones nowadays and is really annoying when I send a text, only to find out 30 minutes later, it didn't even try.
From other threads it seems to be an issue with the most recent update from HTC. Only fix right now is to flash a ROM that isn't running the latest update.

My RN5Pro functions correctly with a Wifi connection, but once I leave my house outside of Wifi coverage, going to an area with no Wifi or mobile 4G/3G/2G signal for several minutes (eg. lifts or basement carpark), when I re-entered into an area with Mobile coverage, the phone would connect to mobile 4G/3G/2G showing full signal strength, but the Internet communication would not function correctly. I can not access most websites, I can hear instant messages coming in (Wechat or Line), but I can not open any messages and I can not send any messages out, applications such as Google Map also can not access any data.
I would the need to manually switch off mobile data, then turn back on the mobile data for the phone to access Internet correctly.
The problem started with MIUI Global Stable 10.2.1.0, the problem remained with 10.2.2.0 and the latest 10.3.1.0.
This problem does not exist with 10.0.6.0 and earlier ROMs.
It seems that somehow the DNS is messed up in the background, mobile connectivity is present, but not all data gets through correctly.
Are there anyone on this forum experiencing similar problems? This issue has been reported by many users in my local MIUI community, but the Mi Service Center is not responding or acting on the problem.
