You can  insert more than one SIM card in the  Huawei P30 Pro and use it at the same time. In this case, you have to do without the use of an additional memory card for apps, music, videos and co.Why is that how you equip the smartphone with a SIM card and what is still to be considered in the Huawei model, you will learn in this guide.

Two phone numbers or more memory?

Before you put your Huawei P30 Pro into operation, you have to think about how you want to use the smartphone. The devices sold in Germany are dual-SIM capable. As the name implies,  operation with two SIM cards is possible . The same applies to the Huawei P30 and Huawei P30 lite. This is particularly useful, for example, for users who want to combine their work mobile phone and the private smartphone in the Huawei device. Even people who travel a lot can benefit from it.

The question of whether you should insert two SIM cards is directly related to whether you want to expand the memory of your mobile phone. The Huawei P30 Pro  accepts only one SIM card , optionally in combination with a memory card or another SIM card. The use of two SIM cards and a memory card at the same time is therefore not possible.

Cards in the right size

The size of the required SIM card makes the Huawei P30 Pro no experiments. As has been customary for some smartphone generations, the Huawei P30 series also uses  the Nano-SIM format . As can be seen in the following picture, there is hardly any edge around the golden chip. If you use dual SIM mode, you must have both Nano SIM cards in this format.

Somewhat more complicated is the memory card. Together with the Huawei P30 Pro, the manufacturer from China has presented a new format for the compact mass storage. The so-called  Nano Memory Cards  are so far (as of April 2019) only from Huawei and can not be used in other devices than the P30 Pro yet. They are also more expensive than the slightly larger and usual microSD cards.

Insert the SIM card into the Huawei P30 Pro

To properly insert memory and SIM cards, you must first move the card slide out of the Huawei smartphone. Useful is  the included tool , the tip of which you just have to plug into the small opening of the carriage at the bottom of the P30 Pro. Then the container should come out a bit so that you can pull it out completely.

Now you just have to put the cards you have chosen in the sled. Pay attention to the beveled corners . They help you align your SIM and disk correctly. Together with the cards, you can now carefully insert the sled into the device again. Once the bin is back in place, you can turn on your Huawei P30 Pro and put it into operation.
