I have a couple of phones I'd like to unlock for international use and I believe only ting do it for sprint mvnos.  Do correct me if there is another to consider!
So assuming I have to temporarily sign up for ting  - is there a way to get the first month free?  How does the referral credit work - will I receive it to use for the first month?  Or am I looking at spending $6+ tax min to do this.
$6 isn't so bad since i have a few to unlock.
Can't believe I want to do this...
