Data problem...

Hi all, i'm currently on MIUI 1.8.26 but this started with 1.8.12 but i don't think the rom is the problem.
So in short, Tmobile gave me a new SIM for idk what reason. My phone just signal just stopped working so i had to get a new one, (there fault) now that i have the new one, everytime i turn on wifi or just after a short period of time i lose data and it doesnt come back. I have to pull battery and take out SIM card for 10 secs for it to return... any ideas?

You mean when you turn wifi on your 4g/2g icon disappears from the status bar?

yes that's what i mean. It just shows the bars. but my browser doesnt work or i cant send mms. basically no data...

Are you actually connected to a wifi network?

No i turn off the wifi to check if i have data but i dont. but yes i am connected to a network when it is on. But still this never used to happen until i got that new sim card...

Yea not sure. If it started when they replaced your sim card then I'd probably just go have them replace it again. In the mean time have you tried a hard reset to fix the connection issue? It might work and save you from having to take out the sim card each time. To hard reset you hold volume up + power for several seconds until the phone shuts off and reboots.

Finally someone has some answers I have been trying to find out what a hard reset is for a while and how to do it.
I AM having the same issue but instead ofwheni shut offwifi it happens when I shut off the phone. I installed EB 1.08 and it is giving me problems. Later I will try a hard reboot.

Official ICS Atrix 2 4G/Internet Issue

I just updated my Atrix 2 to the official OTA ICS 4.0.4 and after it took all day for my system to catch up with the new OS, My data is not working. No internet connective, UNless I'm on wifi. I have never had a problem before until I updated. I use Easy Batter Saver (app) and I reset the mobile network. That didn't work. I tried enabling data through the settings. That DID NOT WORK. I went to the settings --> about phone --> status and the only irregularities I noticed were
Mobile Network State- Disconnected
Sim ID- Not Available
- idk how to take the screenshot.
Any Ideas?
--- Found the answer!
It took a while to figure it out but this was the answer if anyone else is having the problem, It seems that the APN were deleted and the one that remained on mine after the update did not work for data connectivity. This is it. http://forum.xda-developers.com/showthread.php?t=1576199
I used the ATT phone and it worked fine and if you cannot receive MMS make sure to use both of them.
ALSO heres another link for more APNs

ICS data Lost
i lost the data connecion suddendly one day ago, this was working good. i restarted in recovery mode and did a wipe data/cache then add the apn's and now is workng again.

same here,i can not connect to 3G mobile data unless i change to airplane mode (after enabling mobile data and change to 3G network) and then to air plane mode to off.
or to restarting mobile after enabling mobile data and change to 3G network.
i tried 4 ICS radio images,but the same issue !!

i tried stock GB rom, same issue,but i tried another provider SIM with no issues, so , this was related to my provider network.

[Q] Data Connection problem

I am having problem with my data connection on my Samsung Galaxy Tab2. I start using the internet connection with no problems then at one point i lose data connection all other serviced work well sms and calls. In order to get my data connection back i either have to restart phone or else go to flight mode and off flight mode again (flight mode thing sometimes works and sometimes doesn't).
Sometimes, it also says "No SIM Card". This complete issue typically happens when I have the 2G internet ON and the phone gets locked automatically. When I unlock it again, I see these issues.
So far, this issue happened only with 2G connection. Now, today, the No Sim Card message came up when I left the Wi-Fi button on and left the phone for a while. :crying:
I have tried selecting "GSM Only" in the network settings. I am using Vodafone IN (Andhra Pradesh, India) network. All other threads on google suggest flight mode and restart but I don't want to restart so many times in a day... This happens everytime and the frequency is increasing.
Is anyone experiencing a similar problem? Any solutions for these?

do one thing bro! backup all your data, contacts. do a factory reset of your device! all the things will work like butter! use titanium backup available on playstore!

D6683 - Upgrade to D6633 Marshmallow Firmware - LTE Connection

Hi guys.
Just trying to share my observation and explore if we can do anything.
I am using D6683 (I think it is support to be a HK based handset). Using Lollipop, it has been working perfectly but 16GB not enough hence MM function that allow SD card and Internal memory merge is appreciated.
Since Sony decide to ditch us using D6683, the only option is using D6633.
1. Try using MM .575, it has huge connection problem. The phone will just stay in GPRS mode even connected to a LTE network. Driving from one point to another point, will just cause it to data connection to hang. Putting it in airplane mode and anything else won't work. Only reboot works
2. Restore stock and upgrade to .291, first day testing seem to be ok. Got LTE connection. It did try to swing a bit but it has been maintaining well. This i started driving with Waze. Connection start to go haywire, but it will be still try to reconnect. Data are "maintained" to certain extend. Let the phone along for about 2 days, the next thing I realize, only GPRS left. The signal logo got no more H, H+ or LTE. Check the phone service menu and all info confirm the LTE is available. Again a reboot fix the problem.
3. Change the setting to only WCDMA + GPRS. The phone was "perfect". No data hang issue and etc
Need all the sifu help. Assuming if the phone is rooted, how is the phone determine the connection method? I presume that the phone will initialize the modem to dial the connection. Can anyone share anything that we can probably trigger a redial and probably eventually inject into the phone data connection sequence. Again using Lollipop, there is no issue.
Appreciate any comments/advice.
Regards
Dan

Data disappears but signal strength is still full bars

Got the phone this week and a couple days ago something weird happened. I was on Wifi and when i went out of the house, the wifi obviously disconnected. When i arrived at my destination, i noticed that i had no mobile data. Thinking it was just data connection issue, i tried turning on and off mobile data in the notification shade but to no avail. I then tried doing the same with airplane mode and again full bars with no data coming through. I did a restart of the phone and same results. What i did then was a swap of a sim card with my other phone and the mobile data returned! This was an annoying fix as i had to find a sim ejector tool.
This morning, same issue happened again. The only way to get mobile data back was to swap the sim cards back and forth. I do not think this is a hardware issue as the sim cards can be read. Is this a known bug among xiaomi devices or am i missing something?

Having the same issue, sometimes switch airplane mode fixes it, sometimes need a reboot.

Had the same yesterday, toggling airplane mode fixed it... Hopefully a known bug that will be fixed
