Can I Buy an eSIM Before Leaving Dubai?
Yes — and installing before departure is the easier option. Here is what happens to your validity period.

The short answer
Yes. You can buy and install a travel eSIM from anywhere in the UAE, and doing it before departure is the practical choice: installation needs a stable internet connection, which is easier at home than at an arrivals hall abroad.
Does the validity start immediately?
For most travel eSIMs, validity starts when the profile first connects to a network at the destination rather than at purchase — which is why you should install the profile but leave the line switched off until you land. This rule is set by each provider, so confirm it on the plan page before buying.
How early should you buy?
A day or two before departure is plenty. Buying weeks ahead is fine too, but check whether the provider applies any expiry to unactivated plans.
