Anyone swap SIM cards AFTER Activation?

So I upgraded my daughter's account, since mine originally wasn't going to be eligible for a while and now is. AT&T has told me I can get the number for the new 3G S switched to my line, but I have to go to a store and there are still quite a lot of folks at the stores. SO, I was wondering: why can't I just activate the phone on her line, and then once that is done, put the SIM from my 3G into the 3G s, and then give her my phone with my old SIM and restore it from her laptop? Any thoughts?

Success. This worked surprisingly easily and well. I first activated the phone on my daughter's line on her laptop. I then got the message that activation could take up to 48 hours. I then unplugged the 3G S, and inserted my old SIM card from 3G phone into it. The screen showed the message "This phone is activated" in front of the picture of Earth. I placed my daughter's old SIM card in my old 3G, and it showed the same message. I then connected that phone to her laptop and proceeded to do a full restore. All went well. I connected the 3G S to my laptop, and did a full restore. All went well. A couple of passwords for Wi-Fi did not get picked up, and I had to do a VVM password reset, but other than that, they both work fine. When I logged into AT&T, they even showed the correct devices on our accounts. That was surprising.

Can I swap sim cards from an old iPhone 4 to another iPhone 4?

My current iPhone 4 is pretty beat up. My dad's, however, is in phenomenal condition. He actually just upgraded to the 4S and asked me to sell his 4 for him. What I want to do is sell mine and keep his. Is this just a matter of swapping sim cards?

Yes and no. Yes you can switch but the IEMI number is associated with the sim card and you will have some problems. I did this when I had to buy a new phone for my son. He had the 3GS and we just swapped the sim cards. Well his data wasn't working but a call to AT&T fixed the problem quickly after they changed the IEMI number in their system.

how to solve this problem. I don't have any sim cards that came with iphone.
Please help out to solve this problem.
It sounds like the phone was hacked or jailbroken, and updating it locked it to the original carrier. As it is not possible to update to any version other than the current one (5.1) the fact that you updated to 4.1 pretty much confirms the phone was hacked. There is no solution that you can get in an Apple forum.

Tour says, "Insert SIM card" after quick reset

I have a Blackberry tour 9630, and for no logical reason it started saying "insert SIM card" after I reset the phone. I've tried a battery pull, and that did nothing. In fact, I have no idea if my service provider, US Cellular, even uses a SIM card. Is this something I will have to discuss with my service provider or is this something I can fix? I can't seem to even see a SIM card on the phone. In fact, I don't even know where it would be.
Thanks

I also have US Cellular and this problem happened to me while travelling last week I don't know why it did it but I had to go to "Options, Mobile Network" and change the Network Technology back to "1XEV" which returned it to normal. I dont know what caused it to switch to "GSM/UMTS"

I have an Ipod1 with 3G and an unlimited ATT plan. I want to get an Ipad2 - can I swap SIM cards so that my unlimited service will automatically transfer to the new unit?

You don't actually swap the SIM card. For some reason, AT&T doesn't like you to do it that way.
Go to:
www.att.com/ipadlanding
edit payment information link...then update the following two fields:
IMEI:
ICCID:
You get this info from the iPad (1 or 2) select 'Settings' then 'General' then 'About'...
The IMEI and ICCID info is on that screen. No need to swap the SIM cards. This process outlined above transfers service instantly and does NOT change the plan type, billing, user info, or days remaining. Basically anytime an ATT customer wants to move a data plan the ATT iPad web page is all you need. No phone call!
It took me about 3 minutes and worked perfectly.

HT4972 Why won't my iPhone 4 recognize my sim card after update?

Why won't my iPhone 4 recognize my sim card after update?
I updated my iPhone 4 over wifi and it went through the process fine, until it switched back on and now refusese to recognize my sim card!
Any ideas?

Usually this means the phone was previously jailbroken or hacked to unlock it from the carrier it was locked to, and the update re-locked it to that carrier.

Can I swap SIM cards

I've been using a 16GB iPhone 4 for months now. Tonight I bought a 32GB iPhone for my wife. I would like to have the 32GB and give my 16GB to my wife.
If I back my 16GB up and transfer all purchases, etc. Can I simply swap SIM cards, and then restore my data to the new 32GB phone?

If you're using the same iTunes account again you can use the same backup to restore your data and settings. You'll only have to put in the passwords for network and mail again, due to security reasons.
You 32GB will be recognized as a new phone and you can set it up different from the 16GB, if you want to. Backups will be separate from that point on as well.

I have no idea what you mean by that. This is what you need:

Also, is your iPhone 3 carrier locked? If so, only a sim from the carrier your phone is locked to will work.

Thanks Chris for your solution.
But just for you know that I bought Apple to get the 'after service', they should've warn the users not to upgrade to a higher OS if it can caused the phone 'dead'. Mine was totally unusable when it's just been upgraded. It stayed in the recovery mode and couldn't be restored. So I brought it to the nearest store and they did that to me, and eventually the phone is working, only it cannot detect my SIM Card...
The problem is not about upgrading an iPhone to a newer version of iOS. Your problem was upgrading a hacked phone, one of the well known consequences of which is re-locking and/or bricking the entire device when restoring in iTunes. You chose to hack your phones firmware and operating system, so you must accept the consequences of going outside the bounds of normal use that Apple prescribes and supports.
Had you not hacked it in the first place, you likely would have never had a problem, and if you had, Apple would have offered support to deal with it. Your choice, your decision, your consequences.

Question about swapping SIM cards on a Z10

Hi, everyone, I am a non-Blackberry user who works in IT support. One of my clients uses a Blackberry and has often asked me very complicated questions about how to do various unusual things with his device. At the present time, he is considering switching to a Z10, which would be set up using ActiveSync. He wants to know if he could swap the SIM card without having to go through the setup process again. My client travels a lot, and wants to use a local SIM card on an upcoming trip to a very remote area.
I've not been able to find an answer to this anywhere.
This is his exact question: "I just got it from a friend (ATT version) and I am trying to see if I like it enough to switch to it as my primary phone. Blackberry z10 asks you to sign in with your blackberry world ID when you first set up the phone. Question: Would you have to do it again if you put a different simm into it? With iPhone, it makes no difference so long as the device is unlocked—you can then exchange simm cards as often as you want. Would it be the same with an unlocked blackberry z10 (I know it's not possible with the bold 9900 as System 7 ties your ID to the simm card). In short, in blackberry z10, could you exchange the US simm for another country's simm without having to wipe the phone, etc. "
If anyone can shed some light on this for me, I'd be very grateful., Thanks!

Hi and Welcome to the Community!
The key issues are thus:
Ensuring that the device is truly carrier unlocked
Ensuring that the specific device model is compatible with the radio frequencies/technologies that the desired carrier uses. There are 4 different Z10 models:
http://www.bbin.in/en/2013/03/03/4-types-blackberry-z10-models-fits-better/?utm_campaign=4-types-of-...
If both of those are OK (separate research of the desired carriers would of course be necessary), then it is indeed a simple matter to change carriers. For example, I changed from ATT to TMO by simply changing the SIM...no need to WIPE or anything, and my same BBID came along just fine. You should, however, always obtain a properly-sized SIM card from the carrier -- there are plenty of reports of folks trying to use "cut" SIM cards and experiencing errors.
With BB10, it's actually simpler than with legacy BBs. Legacy BBs used the BIS service, which required receipt onto the device (from the carrier data network) of Service Books so as to activate the various services that the user subscribed to. When changing carriers, it often could be that a latent Service Book from the prior carrier causes issues when shifting to a different carrier...and that's where WIPING and such came into play, so as to cleanse the device so that the new carrier could deliver all of the proper Service Books to the device. With BB10, there is no BIS, and there are no Service Books...so all of that complication is eliminated.
But, as always, YMMV.
Good luck!
