What does Mobile’s so-called account manager mean? It’s like the title.

The account manager mentioned by Mobile is not a salesperson~···When we open some services, we will receive some information... It says to check the new business functions. If there are any problems, contact the account manager... This is not Refers to the salesperson's...general problems can be solved by calling customer service at the front desk of the sales hall...but virtual network like VPMN cannot be opened...only the account manager can open it...They usually receive large customers...individuals The mobile phone number is not released to the public...but the office phone number is released to ordinary customers...

General customers cannot contact them...
