Good morning!
I have a problem with a huawei. I put the sim card in the phone, 3G, I put it in another 4G phone.
Good, I go with my phone to another location, I have 4G, at home I don't have 4G on my phone, on other phones with this card I do.
I don't understand where this problem is coming from, why and how can I fix it?

I forgot to specify, I have had the card for about 3 months
