I’d be happy to help with call costs to Mexico! The Pay-Per-Use rate for calls to Mexico with no International plan is $0.65/min to wireless numbers, or $0.49/min to wireline numbers.
With AT&T World Connect Value, your receive UNLIMITED calling to Mexico, 1¢ per minute calls to Canada, and discounted calling rates to over 225 countries, all for just $5/month. For more information, click here.
I hope this helps!
