Can we change SIM card keeping our data?

I am a new BA user. I noticed that to change the SIM card the BA restart " as new" and all data is lost. Is there anyway to change SIM card keeping my data?
Thank you all

Hi
Although I've never done that before (and now you scared me to try it )
I think it's not true.
In order to change SIM, you had to remove main battery. Notice that in this case, the internal backup battery will stand only for few minutes, keeping RAM alive.
Maybe you just weren't fast enough, changing your SIM.
Another thing. When you put main battery back, BA won't use it until you power it on. So putting main battery back, but not waking BA will cause data loss in few minutes.
Maybe i'm wrong.. Maybe I'll play with it later.
Good luck

The only secure way to change SIM is making this with BA conneted to the main power. I try a few times and in all I had my BA hard-Reseted.
Be careful!!

I try on my BA to change the SIM card many times.. and no problem so far the backup batrery is fully charged !!!

Hi again...
I've checked it also.. No data loss..
Dcoelho if you always get data loss when changing sim, it maybe the problem of faulty backup battery (indra9110 suggestion).
Here's what you shold do:
Remove main battery but don't change the SIM !
Just wait minute or so (same amount of time you used when you changed SIMs)
And then replace the battery and see.
If you loose data, it will be obvious that not changing SIM, but only removing battery gets you data loss.
See Settings->System->Power Backup battery power bar.
Maybe it doesn't get charged properly.
Or maybe it says it's charged but it's not (I've seen such case on HP H5550).
Check the thing and report

I have done it many time, iv also dropped the BA the battery has come off, just plug it back in, i find that it only softresests when i remove.

I supose this works similar for Blue Angel as for Himalaya.
Just turn off radio (go into flight mode) before changing sims will avoid your device to hard-reset.

[Q] Strange Arc S signal / battery drainage problem

I bought myself Arc S, it came loaded with .62 firmware. On my initial run, battery ran for about a day, later on for two or maybe even three days. Then I started to work in another country. As far as I remember, battery life was the same, even though the network was not (where I work now is 2G only, in my home country 3G). Then one day messed around with a Xperia S apps, did a stupid mistake and started to get force closes with launcher. I had to repair software.
Since the software reinstallation, my battery life degraded to less than a day without even touching it. Therefore I installed Battery Monitor Widget, to see, what is going on. I noticed, that battery drainage is about 70-110 ma in average, as far as I know, it should be much lower (under 30ma?). I have to say, that I tested this with .62, .42 firmware and it's all the same. When I turn phone to airplane mode, energy consumption lowers to under 5ma - which is normal i guess.
It began to bug me even more, as we bought small alarm clock with radio. I noticed, that when this alarm clock is on, despite from 2 other phones our room, my Arc S is the only phone, which makes this kind of searching-for-signal or calling speaker interference (noise coming out of speaker). My phone does that all the time, even in idle mode. This can be also heard when we have our TV on on. So, if I don't want to hear that, I have to unplug the alarm clock or put my phone into airplane, which sucks.
I asked a guy next building, if he has the same problems with Arc S, and he says that his phone can live up to 5 days with one charge (is connected to the same network provider), so I guess it is not network related?
I wonder, is there a possibility, my phone's radio is broken somehow? Or it was faulty, and firmware reinstall somehow broke it to the end? So that is draining battery all the time - looking for signal? Any way to fix this? Flashing different base bands did not help, tried that already...anybody knows a fix for this, apart from returning it to my provider - since I'm 4 months away from my country
Anybody heard for any similar problem with Arc S?
Thanks in advance! (if needed, I can also post battery usage screenshot, but I think it's not much of a help)

That seems like the issue here if I'm understanding you correctly. If you don't have 3G service where you currently are, and you did not turn off 3G, your phone will constantly try and find a 3G signal.
Airplane mode fixing the issue makes this seem even more likely. Try disabling 3G and see if it helps.

Problem is, that's what I did almost instantly when I came here, I set it to GSM only. One thing I noticed right now, when I check into About phone, under Mobile network type, my Arc S has: UNKNOWN, where my friends HTC says EDGE. Maybe here lies a problem? Why my phone can't detect network type?

Incredibly, I found the reason for my drainage and signal search. When I came into that country where I work now, my provider offered me to turn off data transfer (provider turns it off for me). Of course I did not want any unintended data transfer, so I turned it off by sending sms to service number. After I reinstalled software (that was my first reboot here), phone couldn't find network type for that reason, and was searching for it all the time. Yesterday I allowed data transfer by sms again, phone found EDGE network, can't hear any more noise on our alarm clock and battery drainage is about 4% per 8,5 hour. Excellent
I hope this helps anyone out there with drainage problems.

I think you can also turn off/disable data transfer/traffic with the Data traffic widget, if you want to avoid using data.

xperia arc s
hold up, i dont understand. so im pretty sure i have the same problem. get about 17 hours with berely using my phone on any rom/kernal/firmware. even with data turned off, betterbatterystats shows 'noor unknown signal' and 'no data conection'? i sued to able to get 3 or more days out of my phone??

I think there is an application, which might be keeping the phone alive.

dout it, still drains after a complete rom wipe

[Q] Wifi won't stay turned off after inserting foreign SIM card

I have a SGH-T989, recently unlocked for a vacation to Jamaica. The morning after I put the local Digicel SIM card in, I've noticed that my wifi won't stay turned off. I've tried turning it off in Wifi Settings, through the pull-down menu, through the power widget, and through Juice Defender, and in all of them, the wifi just turns right back on immediately. In the pull-down menu, Juice Defender shows that the "user" has activated wifi; therefore it won't turn it off. I've also tried turning the phone off and on, and with the SIM card taken out. This issue is draining my battery, which sucks here in Jamaica, since plugs and electricity are scarce.
How do I get it to stay off?
I'm running Gingerbread 2.3.6.. Let me know if you need to know anything else.

Try factory reset. BUT make sure that you still have your unlock code so you can put the code in after you did the factory reset.

UGGGGGGGH... last resort...

G3 gets warm while not in flight mode

I'm sorry for the title, but I couldn't think of a better description.
I usually put my D855 in flight mode at night and turn it off when I leave my house - when at home, I only turn WiFi on. While in flight mode after a reboot, my battery life is really good and it doesn't get warm at all. But when I turn it off but proceed to browse through WiFi, it gets really warm and the battery drains quickly. When I turn flight mode on again without rebooting, it still gets warm until I reboot.
This drain only occurs while the screen is on, not while in standby.
This is really weird.
This issue occurs on all roms I've tried (including stock roms) and with the V10 modem as well as with all V20 modems.
Do you think it's a hardware problem? My sim tray is damaged a bit, but that shouldn't cause an issue like that, the sim still gets recognized fine.
I'm using a Telco sim card and it's pretty old (it's still a non-LTE-sim), but unfortunately I don't have any other micro sim cards to try.
Any help is appreciated!
Thank you,
Xerionius

Maybe is battery wrong.

There may be a hardware issue. Did you bring it to the Samsung service? You might get a replacement...
