i think you meant smitty said yes they will cut you off for that. here is the deal with roaming and partner coverage with cricket.
they call it the 50/50 rule it goes like this:

if you have more than 51% of your airtime that is roaming on your acct.in any one month cricket will terminate your acct. for what they call convenience,which is really inconvenience (to you)
sending you a letter saying something like were sorry we think you would be better served by another provider closer to your coverage area or something like that.
so if you are in partner coverage,you might as well save your money.
