FAQ

Quick answers before checkout

When does my plan start?

Your eSIM activates after install and first network attach, depending on the plan policy.

Can I top up later?

Yes. Eligible plans can be topped up without reinstalling the profile.

What if I change phones?

Some carriers allow transfer, others do not. Simmy support will help with the fastest option.

What is an eSIM?

An eSIM is a digital SIM card built into your phone. Instead of a plastic card, you install a carrier profile by scanning a QR code. No post office, no kiosk — just scan and connect in under a minute.

Is my phone eSIM-compatible?

Most phones released after 2019 support eSIM: iPhone XS and newer, Google Pixel 3a and newer, Samsung Galaxy S20 and newer, and many other flagships. Check Settings → About or your carrier settings to confirm.

Are plans refundable?

Plans that have not been installed or activated are eligible for a full refund within 30 days. Once the eSIM profile has been installed, the plan cannot be refunded. Contact Simmy support to check eligibility.

Can I keep my regular phone number while using Simmy?

Yes. Simmy handles your data connection only. Calls and SMS continue to work on your primary SIM. Dual SIM devices let both profiles run simultaneously — local data on Simmy, voice on your home number.

What if I lose signal in a remote area?

eSIM plans connect to local partner networks. Coverage varies by destination — remote or rural areas may have limited connectivity. Check the plan details panel for specific network information before you travel.

Ask Simmy

Use the same language a traveler or AI assistant would use

Simmy works best when the task is stated clearly: buy me an eSIM for Japan, compare Europe eSIM plans for a 10-day trip, create a checkout link for a USA plan, or help me activate an eSIM on iPhone. That language is useful for shoppers, search engines, and ChatGPT-style assistants alike.

Our public pages and Simmy's ChatGPT app are built around the same core tasks: search plans by destination, trip length, and data needs; compare options; move into checkout; and explain activation after purchase.
