Tell me about the disadvantages of a thrifty phone

pu1. You can say that the customer service center is almost out of touch. If you usually use the customer center a lot, you have to put that down

OK

pu2. Since I don't have a membership card, I can't get a discount by using points like a telecommunication company. The fare itself is cheap, so I think I'll get it in cash anyway

OK

pu3. It was inconvenient that I had to know or look for my phone to some extent because it wasn't at the agency when I first joined, and if I had to change my phone, I couldn't play with it because it was not like three carriers and I was assigned one by myself. It's about that much if you have to find it, but there's nothing uncomfortable about making basic calls and using data
