Frequently asked questions
A travel eSIM for Japan is a digital mobile data plan installed on an eSIM-compatible device. It lets you use mobile data in Japan without swapping your physical SIM.
Avoid deleting it while you still need the plan. If it was removed by mistake, contact support before attempting to reinstall it because reuse depends on the eSIM status and plan rules.
Contact Donesim supportAfter successful payment, delivery is usually instant through your Donesim dashboard and may also be emailed. Payment checks, network availability, email delays, or technical issues can cause delays.
Yes. Use the Japan eSIM for travel data while keeping your physical SIM available for calls or SMS. Your home carrier may still charge if its line uses roaming calls, texts, or data.
Use an eSIM-compatible phone or tablet that is not carrier-locked. Compatibility depends on the exact model and regional version, so check for Add eSIM, Add mobile plan, or a similar option before buying.
Check compatibility before buyingOpen your Donesim dashboard and scan the QR code. If scanning is unavailable, use the full LPA string or the separate SM-DP+ address and activation code shown there. Then select the eSIM for mobile data.
The current Japan page offers fixed-data and unlimited-data options. Compare the live data allowances, validity periods, and prices shown before checkout.
Refunds are limited for immediately deliverable digital eSIMs. Contact support with your order number. A refund may apply to a Donesim-side or network-side provisioning failure, duplicate charge, or where required by law; installed, activated, used, expired, depleted, deleted, incompatible-device, and wrong-plan purchases are generally not refundable.
Read the refund policyOpen the eSIM's Usage view in your dashboard and select Refresh Usage for the latest available network update. Reporting can lag until the next network sync.

Activation timing depends on the plan rules. A plan may begin when it is provisioned, installed, activated, or first connected. Review the validity and expiry details shown for your plan.
Review plan and validity rulesSmaller fixed-data plans may suit maps, messaging, email, and light browsing. Choose more data or an unlimited option for heavier app use, longer travel days, or frequent uploads.
No. Current Japan eSIMs are travel data plans and do not include traditional calls or SMS. Use data-based apps such as WhatsApp, FaceTime, or iMessage, and keep your regular SIM available for calls and texts.
Yes. WhatsApp can continue using your usual number while its messages and calls use mobile data from the Japan eSIM.
Installation needs stable Wi-Fi. Check when your specific plan's validity begins before installing it early; when ready to use it, select the eSIM for mobile data and enable data roaming for that line.
Do not delete the eSIM unless needed. Whether setup details can be reused depends on the eSIM status and plan rules, so contact support before attempting to reinstall it.
Ask Donesim supportActual speed and signal vary by location, device, indoor conditions, congestion, and local network conditions; specific speeds are not guaranteed.
A fixed plan is depleted when no data remains, and a plan is expired after its validity ends. The dashboard shows these statuses; choose another currently available plan if you need continued service.
The roaming mark can be normal. Confirm you are in a covered country, mobile data is assigned to the eSIM, and data roaming is on. Then toggle Airplane Mode for ten seconds or restart the device.
Yes. Select the Donesim eSIM for mobile data and turn data roaming on for that eSIM line. Avoid selecting your regular SIM for travel data unless you accept your home carrier's roaming charges.

Donesim does not currently renew or extend an existing plan in place. Purchase another available plan when you need more data or validity.
Speeds can vary, and network partners may control throttling. Donesim cannot guarantee a specific speed; device, location, signal, congestion, and available network coverage can affect performance.
