Failure of Twitter To Call My SIM on SMS Reset

Hi-

This morning (Jun-10) I am unable to get calls from Twitter to unlock accts.

After troubleshooting, I see that Twitter is not calling with unlock codes.

I have done this like +1,000 this year and have a few everyday to deal with.

Has anyone else seen this issue?

Best,

Risk

PS: This is not really an sms issue, its a not calling issue
