The memory in my phone is slowly filling up (huawei mate 20 lite)
Aren't there these extended memory cards that you put in in addition to this nano card?
Is there anything I should watch out for? And where can I get them cheaply?
Ask your electrical retailer for a microSD card with a high storage capacity and it should preferably be class10. It is one of the fastest read and write speeds

This is very good, for example
The memory of your mobile phone can only be expanded by 256GB. It should definitely be a Class 10 MicroSD card.
