You can find the option under Settings > Phone > SIM PIN.

There is an Apple support document on how to do this. You don't need to keep a sim in the phone but you need to put one into it to activate it before taking it back out. Here's the procedure for 3G and 3GS: You can use any SIM card associated with the carrier that your device supports to activate the phone. Simply place a SIM card from the last ...

This is, unfortunately, expected behavior. Whenever you activate an iPhone (which you do as part of an OS install) it talks to Apple's servers and does various things like exchange crypto certs for APNS, etc. It also checks the IMEI of the phone to see what carrier Apple sold it to, and validates the SIM is valid for that carrier (if you buy an unlocked ...

Go to your local GSM carrier (AT&T in the US) and try to reactivate it. A couple of possible scenarios seem likely: The phone is recent enough to be on a contract - they'd still have the payer on file and you could contact them about giving them the phone back or them cancelling the contract (or you taking it over). The phone is free and clear - this ...

According to this article, the problem isn't just the size. It turns out, as well as a smaller size, the Nano SIM is reportedly 15% thinner than the Micro SIM cards. So even if users cut the Micro SIM to Nano SIm size with a knife or nano SIM cutter tool, the Sim card would still be too thick to put in the iPhone 5.

Yes, you can use the device as if it were an iPod Touch without cellular service. No need to remove the SIM. It will automatically be deactivated when your new phone is activated. You can also purchase a prepaid SIM from a service using provider network to which the phone is attached if you'd like to use it as an emergency or burner phone. For example, h2o ...

gentmatt's answer is correct, however if you don't need to make phone calls at all you can also just turn on airplane mode. I have done this many times abroad. Turn on airplane mode in settings, then turn wifi back on. Your cellular signal stays off.

PUSH! The old way was to insert the tool at an angle and kind of push sideways and pull out at the same time, using leverage, and the tray would hang onto and come out with the tool, but with the new iPad (2012), simply insert the SIM eject tool straight into the tiny hole (straight being the way it enters with the least resistance, i.e. perpendicular to ...

iMessage can also register email address (like your Apple ID), that's how it works on iPad and iPod Touch. So it's completely normal to be able to send iMessages with an SIM-free iPhone. As long as you are connected to a WiFi network.

No - the sim card only provides an ICCID number to the phone. That number is read once per boot as the phone just uses the sim to identify what account to bill for service when registering with the nearby cell towers (IMEI and ICCID together let the system know what number to assign your phone and who to bill). Something else must be causing your observed ...

I bought an old, used AT&T sim card from eBay for $4, inserted it into the phone, and that worked fine -- now the phone can be upgraded to new iOS revision, even though I never plan to use it as a phone ever again. As I learned the hard way: do not remove and throw away the AT&T sims from your old iPhones, no matter what!

The iPad with 3G is sold unlocked. In the UK, the iPad with 3G will work with Orange, Three, O2, and Vodafone. To be pedantic, the iPad's 3G connection will not work with carriers such as T-Mobile USA, which in part uses the 1700 MHz frequency for 3G. The iPad with 3G supports the necessary frequencies to fully work in the UK with Orange, Three, O2, and ...

No - if the device is waiting at the activate screen it won't run normally. Yes - once the activation is done, you can pull the SIM card. Activate means that the OS becomes usable. Unless (and until) your phone gets jail broken or authorized unlocked (contact your carrier), by design you need a carrier SIM to activate the phone after each restore. Major ...

Here are the steps to use either an iPhone or an iPad without cellular activity. Open Settings. Turn Airplane Mode ON. This will also disable Wi-Fi but we will re-enable it in the following step. Tap Wi-Fi and you will be directed to another screen. From there, turn it back ON and select the network you wish to connect to (note: it will automatically ...

The other way around you can use an adapter or get a replacement SIM as well. It ...

Without going into the technical details, iOS ships in a deactivated state and needs to contact an activation server to determine the carrier and locking status each time the device is restored. iTunes performs the unlocking of all phones less than iOS 5. With iOS5, the device can self activate or activate through iTunes. When a device is sold, it enters ...

You'd need an adapter like this one to make it fit, but it should work.

Take it to the Apple store if there is one near you. Usually they will switch out the phone if still under warranty.

If you have done a full restore (ie reset the software) and the sim card is working in other phones then the phone hardware is faulty.

The iPhone 4S is a world-phone, compatible with Verizon and Sprint's CDMA networks in the US and GSM networks worldwide. It has a micro-SIM slot for connecting to GSM networks. Most phones sold in the US are locked to the carrier you buy it from, you may have luck getting them to unlock it so you can use a different SIM. Unlocked iPhones are (tautologically) ...

Will the iphone get 4g speeds No it won't. iPhones, even 4 and 4S, are not 4G devices. The 4 is for the iPhone fourth generation, but they are in reality 3G devices. So you won't get better speed than 3G (for sure). I'm not sure for the network itself since I'm in Canada and I don't look at US providers very often. From memory T-Mobile has a different ...

No SIM card is locked to any phone. The SIM card will work in any unlocked device supporting the frequencies used by the carrier that issued the SIM card.

The IMEI shouldn’t change when you upgrade the phone, at least here in Europe. Mine is still the same. Update: Upon some reading around, it turns out that if you “hack” your phone, (maybe in the past), an update would change some IMEIs, and AT&T would therefore invalidate the SIM. Be careful with what you do :)


3

Yes. No it won't affect your phone. An iPhone requires a SIM to activate. If the phone was locked to a specific carrier, it would require a SIM from that respective service provider. Since your iPhone is factory unlocked, any SIM (provided it's a micro-SIM) will suffice for activation. SIM cards to do not affect your device. You could get SIM cards from ...

Official iPhone unlocking only comes from Apple. So you'll have to go through your service provider if you want to unlock your phone. Your carrier will then contact Apple about unlocking the phone. Your iPhone will be identified by its IMEI number. Once this is done, your carrier will contact you (it can take up to a week). Then, you will have to restore ...

Yes. You can use your iPhone's Wi-Fi without a SIM card, no matter where you are. If you still want to be able to make calls, but avoid celluar data (data roaming) you can choose to disable just this feature. You can get further information from Apple's support website at iPhone and iPad: Using cellular networks while in another country. If you do not ...

This is the same set of steps you would use if you had a sim card, it's more about clearing the account that device has registered with the iMessage service. Try to turn off iMessage completely, totally log out of the system in Settings > Messages. When you re-enable it, ensure you log in with your own Apple ID. At this point, you should be able to ...

That chipset is capable of running a hell of a lot more than The Sims, however you haven't stated your OS version, processor, or memory, but based on what MacBook systems have that graphics chipset, you shouldn't have any problems. The minimum specs for the game are: Mac Mac OS X v10.5.7 or later Intel Core Duo processor 2GB of RAM 6.1GB ...

I have two ideas for you: 1) There's a UK mobile network called Ovivo, basically, you order a sim with £10 on it once, and you'll have 500MB of mobile broadband for your grandma's iPad forever. She'll also be able to use the £10 for additional broadband if she runs out (either by pre-purchasing some — and maybe you could do that online for her), or it'll ...
