Pinephone inexpensive carriers and free carriers

[linux_n]

Hi is sister mobile or tello mobile compatible with pinephone? Also TextNow is now free without WiFi over the Nationwide Sprint Network would that be compatible with pinephone. I put my IMEI number on this 3 websites and it said is compatible but want to check with you guys first. Sister mobile is $5 per month and tello mobile is also $5 per month. Textnow is free unlimited talk ad unlimited text you only have to pay for the sim one time $9.99 activation kit. I am looking for a inexpensive phone service or free service for pinephone because i don't use alot of minutes or text on phone so low minutes would be ok. Let me know if any of these 3 phones services would be compatible with pinephone if not which do you guys recommend?

Ok.
