New ee SIM - impossible to register. Login to "Myee account" invariably says "invalid details" despite repeated attempts with CORRECT details. Online registration invariably brings message "that didn't work" or "system can't process this information at this time" despite repeated attempts to register with CORRECT information. Try to call 150 - "call not allowed" Ring help number on landline - automated message to "use online registration system". Money I put in to start using ee almost entirely used up in futile attempts to register and actually use ee. Many hours and many ££££ wasted on ee so far. I know I'll never get them back (ee seems to make sure you can't communicate with them) so I've cut my losses and will move back to my old service provider. Hard to believe such complete non service exists in this day. Slick advertising. Abominable service. One star is one too many.
