I bought my Samsung Galaxy s2 online last December and I've been having issues with it for the last month or so.
The phone keeps on displaying NO SERVICE at least 2-4 times a day and would require to be switched off and on in order to work (note occassionally it'll have to be restarted serveral times in order to get rid of the NO SERVICE problem).
I know for a fact that there is service in my area as I have 3 family memebers who are with Vodafone and don't have the same problem as me.
Can someone please advise me what I should do to fix this problem?
From what you've described, it's most likely going to be one of three issues: a faulty SIMcard; a software bug that can be fixed with a reinstall of the software or a physical fault with the handset that will mean taking the handset to your nearest Vodafone store to be sent for repair.
The first step you should take, is to ensure that you backup your handset, this will ensure that you don't loose any important data.
Once you have ensured that all of your data is backed up, a SIM swap will ensure that the SIM card is not causing the issue. If you're close to a Vodafone store, they can do this for you on the spot. If you're unable to get to a store, then I can arrange to have a blank SIM sent to you for us to do a SIM swap.
If the SIM swap doesn't fix the issue, the next step is to do a wipe and reinstall of your phone. This completely erases your handset and then re-installs your software, returning your phone to it's original state. You can do this directly from your handset from the settings menu, or via your computer using Samsung KIES.
Once this has been completed, it's a good idea to delay installing applications on the phone for a few days to see if the issue has been rectified. Then start adding your applications slowly, to see if a particular application may have been causing the issue.
If the erase and re-install does not fix the issue, then it is most likely that there is a physical fault with the handset, and the phone will need to be sent for repairs.
Please keep me posted on how you go with these steps, let me know if there's anything else that I can help with.
I think I have the same problem. Anytime I am using my phone for more than about 5 minutes, I'll lose my data connection and then my network connection such that calls are dropped. txts wont send and I have no internet connectivity. After 10 minutes or so it will come back online (or if I turn the phone off and restart it. While its offline I go to the settings and the it shows there are no APN's listed. When it comes back online my vodafone apn has miraculously returned. I have been using the same sim card for almost 2 years. Do I need to get a new one?
And if my phone is blanked and restored to factory settings will I have to download all my apps and settings again?
My advice is to always get a new SIM if you update your past 1-2 years. The technology is moving so fast that your SIM needs to be changed to keep up with all the changes. This is a common issue with a lot of people change to "smart phones".
Sometimes when a network provider updates their technology you may need to update your SIM.
If you are going to be doing any sort of factory reset or firmware update you should always backup your phone.
I got my galaxy note on 25th March 2012. Had lots of issues.
- When on a phone call, my headset restarts itself (3-5 times a day).
-Sometimes when messaging friend, the screen goes blank and cannot perform any function at all, I could not turn off. (Got my battery out and back again to enable it to go off).
-Very often the phone can go into NO SERVICE (at least 3- 5 times aday). Receiving voice mail msgs everyday from friends and work.
So I went to the nearest Vodafone store and they requested to sent off for warranty repair. Done. But the issues didn't solved. Still having the same problems everyday. It's really ANNOYING. I called customer service and was asked to sent off for repair again. This is not good! What if the 2nd, 3rd or 4th repair doesn't solve the issues?
Thanks. But I will be going overseas in a month time, hopefully the issues resolved as soon as possible before I leave.
A friend of mine have the similar problem and got sent off second time with the unresolved issues (which took more than two weeks time) and she sent off again last week for the third time repair, she is really unhappy, and don't know long it would take this time.
I can assure you that your issues will be resolved as soon as possible. At the moment your best option is to send it off to repairs for a second time and specify what the issues are and make sure they are noted so the repair centre and focus on them and try to repair them.
In the meanwhile, don't hesitate to ask questions.
