I have a unlocked Samsung Focus v1.3 with Mango update. I am a 3G SIM card (Airtel 3G).
Sometimes when I am trying to enable data connection, phone is refusing me to do that. The setting shows data connection ON, but 3G symbol on top does not appear.
This happens even on multiple retries and when signal strength is full. Using the same SIM card I am able to connect to internet using my older Nokia phone without any issue.
The only solution I have been able to find is to soft reset (restart) the phone. Then it is able to enable data connection. I also think that this issue appeared after I updated it to Mango. With stock NoDo update it was working fine (though I had this phone only for 2 weeks before updating to Mango).
Is anybody else also facing this issue?
yes i am having a similar issue with my focus, it is unlocked for use in the UK on o2 but when ever i turn my data on it says its connected i have the 3g symbol and everything but when i try and go on the internet it has not connection to resolve this problem i delete my apn and enter it again but that dose not work sometimes and it is really annoying
many thanks if you can help me
^^ Thanks for confirming that I am not the only one facing this issue. But still it is weird that only a few might be facing this issue.
I am still trying to find out the exact solution, so whenever I find it I will post it here.
APN settings? is the sim card for that device originally?or carrier specific"?

I have used correct APN settings for my Service Provider. Hence on a good day, I am able to connect to Internet. I have also confirmed the settings from CC.
But as I have described earlier, sometimes phone just doesn't turn on data connection. This happens without any specific reason. On other forums too people are reporting the same behaviour.
Same problem here with Movistar in Colombia
Sent from my Samsung Focus using Board Express

That has nothing to with problem I am facing. This setting for radio is for FM radio and not for mobile radio. You might face the issue again. Sorry but that's the truth!
did u try another sim card?
A friend with same data plan?
And another operator sim?
When i changed wifi to data it came to me, there was a app for that first it closes wifi then open data connection. For wifi again, first it closes data connection and opens wifi.
I got same problem. Using unlocked focus with airtel connection india. On a good day the phone will work with gprs/3g just fine. But occasionally connection drops and the phone won't reconnect. I have to manually restart the phone to connect to internet once again. Any solution for this? I guess people in US aren't facing such an issue..
I have the exact same problem. This problem arises only on DATA connections!
Using ATT Samsung Focus v.1.3 on Idea Cellular Sim Card in India
Hello everyone.
I've had the S3 Neo for a week and have been enjoying it so far, but I realized something weird. I have two sim cards, one is a corporate number with 3G and the other one if my personal number, also with a 3G plan. My phone only connects at speed H/H+ on the sim in slot 2, doesn't matter which sim, the sim in slot 1 only connects to Edge.
Before someone says that the phone can not connect to two 3G networks at the same time, I know that. For the tests I made I changed the configuration, leaving one sim with only GSM connection and the other one with WCDMA.
Does anyone know what could be the issue and how to proceed to fix it?
Thanks in advance.
No one?
I just need to know if there's a fix for this or I have to send it back to the store.
Appreciate any help.
I am using two sims in india SIM1-> airtel(2G mode) and SIM2->Jio ( LTE mode).
This message pops up frequently at the bottom of screen.
Any one aware of how to fix it ?
I am also facing the same problem in S7 Edge. If you are able to find a solution please share it.
jio sim seems to be the culprit kick it out of the phone and problem solved, was facing the same problem one of my two sim cards was a jio sim, did a little research and found that mostly those who were facing the issue were using jio as one of the sim cards.
The thing you need to do is go to Setting> mobile and networks > select network operators> choose the sim card which you use for data usage > select on ( Select automatically- automatically select preferred network)
I satisfied with this solution, look that you might be too.
Me too facing this issue in my j7. Using jio in slot 1. Anyone found solution ?
I called to jio customer care but they told me that your sim card is damaged. Visit nearest center to issue new sim card.
But i dont think this is the solution.
Most likely it's CSC problem , You may flashed a different CSC than yours
Check your APN settings and see if they are properly set.
hi! Has anybody found a solution to this issue? I bought a #Note9 yesterday and same issue exists. This happened on all my past devices too Samsung S7 and LGV20. I once changed the SIM card still no luck. Any update on this matter is greatly appreciated.

Via your networks settings or Google search .
Use auto registration.
Thankx all
I tried what you said and nothing worked. I found out that with SIMs from certain mobile carrier the network signal is weak and sometimes not registered. What would be the problem?
Try a different modem .

Hello. I have the problem occurred when there were two SIM cards in the phone and the Internet was from the second SIM card. if leave one SIM card in the first slot and the second remove the problem disappeared. It was found out that this depended not on the phone but on the specific SIM card and its firmware. what may have a you problem can not tell. im said that he knew. thx.
Apparently from the tests performed, it is a problem in the LTE mode, since I switched to UMTS (3G), I no longer had connectivity problems. I hope that the problem can be corrected by Samsung, in a next update.
PS: Needless to say, I stopped having 4G communications !!!
Is or was your problem in any way similar to mine?
