Activate the second iPhone for sending SMS with the Telekom MultiSIM card

Operate the second iPhone with the Telekom MultiSIM card.

Whenever you get your new iPhone, you have to think about what to do with the old one. I have currently ordered a multi-SIM card from Telekom for my second iPhone to continue using it as a phone, for photos and for navigation. With Telekom, you can use both phones to make calls using the same number, so both iPhones will ring when you receive a call. Sending SMS and MMS is only limited to one card. That means you have to decide which will be the main phone that will also “handle” the SMS messages.

GSM codes for telecom

To define which iPhone is responsible for sending and receiving SMS and MMS, enter the following GSM code on the number block in the phone, to activate SMS / MMS sending on the iPhone:

* 222 # and then press the handset symbol

A message should now appear on your screen that this phone is now activated for reception.

Do you want to know what the current status of the phone isthat you have in your hand, then there is this command:

* 221 # and then press the handset symbol

In some cases, switching does not work immediately. Then it is advisable to reactivate the SMS reception via * 222 # on the old iPhone and then to activate it again via * 222 # on the new iPhone. For most people, this solves the problem.

Why is the SMS switching important?

If you're asking why this switch is important even though you're not texting: Well, for one, use the messages App of the iPhone, the SMS may be used as an emergency solution if it does not have an Internet connection via the wireless network. On the other hand, WhatsApp is quite petty when changing the phone and wants to carry out a verification (in my case, despite the same SIM card). You get a 6-digit code from WhatsApp via SMS - and it should arrive at the right phone. :)
