# Physical SIM Card Activation

When you purchase a physical SIM card, it typically takes 1 to 2 weeks for delivery to your mailing address. Once you receive your SIM card, please activate it by visiting <http://1psim.com/activate> and entering your activation code.

**What is an ESN Number?**

The ESN (Electronic Serial Number) is a unique identifier for your SIM card. You can find the ESN printed on the back of your SIM card.
