The SIM extraction tool usually comes packaged with your mobile phone. It contains a sharp point that fits in the pinhole of the SIM tray. If you don't have the SIM extraction tool, you can use a paperclip or pin.
This will eject the SIM tray, and allow you to remove it along with the SIM card.
You can use the same SIM extraction tool or paperclip to eject the SIM tray on the new iPhone. The SIM tray is usually located on the right side of iPhones.
After you eject the tray, use your fingers to pull the SIM tray out of the phone. Turn it over to dump the SIM card out of the tray.
The SIM tray has a slot in the shape of the SIM card. Align the notched corner of the SIM card with the notched corner of the SIM tray slot, and make sure the gold chip is facing down.

Place the new iPhone SIM tray back in the phone. With the SIM card in the new SIM tray, you can now place the tray back in the new iPhone. Press down to lock it in place. When you power on your new iPhone, it will be using your mobile phone number and any other information you have saved to the SIM card.

1
Check your current service contract. Before switching to a new mobile service provider, dial 611 on your mobile phone to contact customer service for your current service provider. Ask if you are under any contractual agreements with that service provider. If you cancel your service while you are still under contract, you could be charged a termination fee. If you are still under contract, ask how much longer you have until the contract is up, or ask how much the termination fee is.
- Do not cancel your current service. If you can cancel your current service, you will not be able to port your number to a new service provider.
2
Check your number's porting eligibility. If you are thinking about switching to another mobile carrier, and you want to transfer your number, check to make sure you are eligible to transfer your number to a new service provider. Most mobile service providers will allow you to transfer your number as long as they offer service in the same geographic area. The following links will allow you to check and see if you are eligible to transfer your number to a specific mobile carrier.
- Check your number's eligibility on AT&T
- Check your number's eligibility on Verizon
- Check your number's eligibility on Sprint
- Check your number's eligibility on T-Mobile
3
Contact the new mobile service provider. After you have selected a new mobile service provider, contact that mobile service provider and tell them you want to port your current number. You may need to provide your account information for your current service provider. If you have a new iPhone in hand, you may need to provide them with the ESN/IMEI number for the phone. The new mobile service provider will contact your current service provider and begin the porting process.^{[2]

- AT&T: 1 (800) 331-0500
- Verizon: 1 (800) 922-0204
- Sprint: 1 (888) 211-4727

When you transfer your number to a new mobile service provider, they should send you a new phone or SIM card in the mail. When you receive the new SIM card place it in your phone. If you are getting a new iPhone from the service provider, it will already have a new SIM card in it.
The porting process should happen automatically. However, it's a good idea to contact your old wireless service provider and make sure there are no fees or outstanding charges that you need to take care of.

Can you transfer a 16GB SIM card to a 32GB iPhone?

Community Answer

Yes, you can. Just as long as the SIM card you are using has a plan because it is only cellular data.

Contact your current carrier for a PAC (Porting Authorization Code), insert your SIM into the iPhone or provide the PAC when activating a new SIM, and follow your carrier's instructions to complete the transfer.
