Thanks, but the problem is the specific phone oneplus. I was confused by "but it was a one year worldwide data sim" I didn't know that AIS sold any worldwide data sims- do you mean sim2fly? How were u able to get a one year version I'm only seeing 7 or 15 day packages on their site (have u used it in the US?)

I too, had a phone (samsung s8) that worked with the AIS sim card so I did not anticipate any problem when I switched to the new phone - but it just won't work.
