Step-by-Step
To change the Electronic Serial Number (ESN or EIN):
The customer should enter the number on the bottom of the terminal. The label is a four-digit
EIN, such as 0116. After entering the number, the customer can view it by going back into
Function 11 and reviewing the initial screen under cell config.
The 214 in the ESN number indicates which cell manufacturer created the cell modem.
Hypercom uses Standard Communications to manufacture its cell boards. The cellular provider
needs to know this information.
