Cant Access My O2 Account

[Tillerman]

Hi, I pay monthly for a Sim Card that goes into my Router for mobile Wi-Fi on a boat to work my Laptop.

When I try to access my O2 Account they send me a 6 Digit Security Code to the phone number on my Sim that's in the Router, so I have no idea what the Code is, as I don't have a phone with O2.

There is no option to change the phone number, except to send more codes. 

O2 think that the Sim is for a phone, even though I keep telling them its for a Router.

Any ideas how I can get into my account, thanks in advance.

@Tillerman The only way to get the code is to put the sim in a phone.

Ok thanks Bambino

Your router has a control panel which when accessed, will show you any sms messages received.
