RoboCall / Spam Call Advisory
SIM Card Phone number is randomly assigned when you activate your SIM Card.
We have no control over the phone number you are issued, such as if it is a recycled number or new number.
There is also no way to tell if the number is new or recycled.

You may occasionally receive spam calls from scammers.
Please understand that spam call issue is a known problem in the United States and affects every single carrier or telco.
There is nothing SIMCARD.SG can do about it since it affects every single phone number in the US.

You are encouraged to install call blocker software or to ignore those calls.
Most of the time, the calling will stop after a few days if you ignore those calls.
