Who called from 5512550750

I need information for this number, because it show on my bill a lot of times  (551)255-0750

This number shows in our T-Mobile bill (52-551-255-0750) every month and we don't recognize the number!!

En mi factura de telefono me están cobrando llamadas que me entran de este número y yo no lo conozco alguien me puede ayudar.

This number - 525512550750 - shows up as a roaming call on my T-Mobile bill. T-Mobile is charging me $1.49 a minute for 60 minutes worth of Mexico roaming calls. Any ideas?

52-551-255-0750  This is a Mexican tower call.  When you are in the vicinity of Mexico, such as San Diego, on occasion your calls will pick up a Mexican tower instead of a USA T-Mobile tower.  It is a common problem but a pest to deal with.  Every time you get charged, call up T-Mobile and get credit.
