The US number we provide is only a virtual number.
It is a call forwarding service that reroutes numbers to your Israeli phone. It is not connected to your sim card and therefore is for incoming calls only and cannot show up in your outbound caller ID.
Your outbound calls are being made from your Israeli provider and will show up as an Israeli number.

Please note: If you have a virtual number, remind those contacting you NOT to return your call using the contact information in missed or received calls or else they will be charged for calling an Israeli cell phone.

The Cellular One Talk and Text plans are the only plans that have an international number that will show up on the caller id when calling internationally.
