Change phone number on WhatsApp: You have to pay attention to this
If you change your phone number, you don't have to worry about your own chat messages. With WhatsApp it is very easy to swap your old phone number for the new one. t-online shows you step by step what to look out for.
There are various reasons why smartphone owners switch phone numbers. Often a new contract is the reason. What many users forget: The popular WhatsApp messenger service only works with a stored number, even if an Internet connection is actually required to send the message.
So if you change your phone number, you also have to replace the old number with the new one on WhatsApp. t-online shows you step by step how you can easily change your phone number. It doesn't matter whether you use an iPhone or an Android device. The instructions work equally for both operating systems.
By the way: If you want to change not only the telephone number but also the device, you have to consider additional things. Read here how the move to a new smartphone is very easy.
Check preparation and number
Before you start, there are a few more things you should consider so that nothing really goes wrong when you change your phone number. It is important that you make all the settings before you insert the new SIM card in your device and verify it with WhatsApp. This ensures that all contacts and chat histories are not lost when changing numbers. Please also note that your mobile phone can receive SMS and phone calls and is connected to the Internet.
In the next step, check whether your old number is really stored on WhatsApp:
- To do this, open the settings in WhatsApp and tap on your profile.
- The phone number currently being used is displayed under your picture and name.
- When changing the number (see below) you should enter it as the "old number".
Create a backup
Before switching, you should be on the safe side and save all data of the WhatsApp account in a backup.
- To do this, simply go to the settings of the app.
- In the "Chats" submenu, then tap on "Chat backup".
- With "Create backup now" you can now make a backup copy of all your data, chats and contacts. You can determine beforehand whether videos should also be included in the backup.
Insert SIM card and change number
Before you can store the new telephone number on WhatsApp, you must first remove the old SIM card from the device and insert the new SIM card. When this step is done, proceed as follows:
- Open WhatsApp and go to Settings.
- Then tap on the "Account" tab and then on "Change number".
- A window with fields will appear. In the upper one, enter your old phone number with which WhatsApp was previously linked. Enter your new number in the field below.
- In order to finally change the number, WhatsApp now asks you to verify the new number. For this you should now receive an SMS containing a link. WhatsApp should normally recognize the link automatically. If not, open the SMS, click on the link or enter the code manually in the "Verify phone number" area.
- Now the messenger can be used as before, only with the new number.
You can also find step-by-step instructions with pictures in the slideshow above or here.
If a contact writes you a message on WhatsApp after changing the phone number, it will be sent to you as normal. Only SMS or phone calls are not put through to you. Therefore, it is important to let family and friends know about your new number.
To do that with WhatsApp, simply activate those contacts who should be notified after the third step when changing the number. This can either be all contacts, contacts you have a chat with, or custom contacts.
By the way: Within group chats, the other members are automatically shown a message that a group member has changed the number.
