No, whoever is in charge of writing High Priority Memos on cx accounts at Metro by T-Mobile / T-Mobile Corporate made a typo in the Memo itself which links to a spam domain. The memo also claims this exact message was also sent to customers phones.

Typo URL in internal account memos + texts sent by the company to subscribers : http://metro-tmo.co/CustInfo

Actual legitimate URL they meant to put : http://metro-tmo.com/CustInfo
