To change SIM cards on iPhones, you should ensure your iPhone network is unlocked, as some iOS devices are locked to a particular service provider. This makes it impossible to use a SIM card of another network on your device. Here's how you can check if your iPhone is carrier-locked:
Step 1. Open Settings on your iPhone. Click General and select About.
Step 2. On the About page, scroll to Network Provider Lock/Carrier Lock to check the status of your iPhone network carrier lock.
Note: You must unlock your iPhone carrier if it is carrier-locked. You can use a professional iPhone unlocker or contact an authorized network provider's shop.
The most common data on old SIM cards is phone numbers from your contacts list. You have to transfer phone numbers from iPhone to iPhone and back up this information using these steps. The process may vary depending on your phone type:
For iPhone:
Step 1. Open the Settings application. Tap on Contacts.
Step 2. Select Import SIM Contacts at the bottom of the menu.
Step 4. Choose where you want the contacts to be imported.
Note: iPhones do not store contacts on SIM cards. For transferring contacts between iPhones, it's better to back them up on your computer or iCloud.
For Android
Step 1. Open your Contacts application.
Step 2. Select Settings (usually represented by three dots in the upper right corner.
Step 3. Tap Manage Contacts and Import/Export. Choose Import from SIM card.
Conveniently, you can transfer contacts from Android to Android/iPhone directly with EaseUS MobiMover. You can also upload them to Google Account, which provides up to 15GB of free storage.
Before you land in a situation where you lose all your contacts in a snap, ensure all your connections are securely backed up. After all, some numbers are too vital to forget. Note down essential numbers, like emergency contacts or critical customer service lines, on a spreadsheet or upload them to virtual data backup so you can still reach out when needed.
Whether you use your phone's cloud storage or a third-party service, this safeguard ensures you won't lose touch with the people who matter most. That way, you can still access the essential phone numbers even after you change SIMs. This ensures you don't misplace any vital phone contact after the change is complete because there will always be a backup stored somewhere different.
When you change your SIM card, ensure your family and loved ones have your updates. Share your new contact details, including your unique phone number, so they can keep reaching out without missing a beat. Also, you must update your number for essential services, including banks, schools, doctors, payment providers, deliveries, utility companies, etc., to avoid service interruptions. This proactive step ensures you will receive all essential communications and notifications.
Some connections are just too vital to leave to chance. Contact individuals or institutions with whom you have critical ongoing communication, such as employers or business associates. Tell them about the change to avoid disruptions in your professional relationships.
Once you have informed your close associates about the decision to change the SIM card and get a new phone number, follow up with them to see if they have received the message. While sharing your new number is helpful, you must notify people when the date will be and reconfirm when the change is complete.
The list of important people may include your core family members, best friends, and any essential utility service provider like your internet company. Follow up with these people to rule out any confusion over the change and verify that everything is sorted out admin-wise.
If you are considering a new mobile service provider, always compare plans and research coverage areas to pick the best carrier for your needs. This can unlock new features and possibilities. When you swap SIM cards for a new one, ensure the new SIM card is compatible with your phone's model and the carrier you plan to use. This problem usually arises with iOS users as all modern iPhones use nano SIM cards. So before you proceed to insert the SIM card into your phone, ensure the size fits perfectly.
While switching SIM cards is easy, remembering the passwords is crucial. You may struggle with losing all the essential access to apps you have gotten used to when changing SIMs or putting them into a new handset. Finding yourself locked out of your banking app is less than ideal. So, before switching the SIM card, ensure you know every password and write it all down somewhere to have a secure access method. This way, you won't be caught off guard when logging in.
If you cannot remember the logins, this is a great opportunity to reset passwords while you're still in your old and familiar setup. You have access to certain things to help the process go more smoothly. Nothing is more frustrating than being locked out of everything because of authentication factors and blocked passwords holding you back.
When you change SIM cards, you must update phone numbers linked to accounts receiving verification and 2FA codes. You can turn off 2FA, change your number, and then turn it back on to ensure account access.
For example, here's how to manage phone number changes for apps such as Viber and WhatsApp.
Changing your SIM card is pretty common, but taking protective steps is essential to ensure no data loss. Now you know what to do before changing SIM card. The additional factors of sifting through the admin and making sure you don't get locked out of any apps are essential, too, but these are all manageable tasks if they stay on the radar. Remember to tick everything off the list, and you will have a smooth transition into a new SIM in no time.
