eSIM not connecting? Here's what to check

No. A phone can store several eSIMs, so keep your Taiwan eSIM — don't delete it. After installing, go to Settings → Cellular (Mobile Data) and switch Mobile Data to the new eSIM, and keep your Taiwan number on for texts. Turn off Data Roaming on your Taiwan number to avoid roaming charges. Some Android phones can only have one eSIM active at a time; just switch to the travel eSIM when you go abroad.

Dial *#06#: if an EID appears, it does. Supported models by brand are listed on our "Phones that support eSIM" page; Samsung phones sold in Taiwan only have eSIM from the 2026 Galaxy S26 series, Z Fold8/Z Flip8 and similar.

No. Contract phones or phones locked by a foreign carrier must be unlocked by that carrier before you can install another provider's eSIM.

Check your spam folder first. If it's not there, go to Find my order and enter your order email and order number to resend it to the same address; members can also see it in their account.

Go to the Find my order page (/lookup) and enter your order email and order number; the installation email will be resent to the same address. Members can also view it in their account. If you deleted an installed eSIM, contact support at service@yunelo.tw.

Tap Check usage on your eSIM page or on the order page in your account. Usage usually appears after you start using the eSIM.

There are two kinds of plans: Total data: one data allowance for the whole trip (e.g. 20GB / 30 days). When it runs out you can't go online, but some plans (currently Japan) let you add more data. Unlimited: a set amount of high-speed data each day (e.g. 2GB a day). After that, speed drops to 1Mbps for the rest of the day — you stay connected, and full speed returns the next day. 1Mbps is fine for maps, social media and LINE calls; video will be slower. Unlimited plans are currently available for Japan, South Korea, Thailand, Vietnam, Hong Kong, China (Singapore IP) and the United States, with 1GB–3GB of high-speed data per day depending on the destination — see each destination page.

Keep Data Roaming off on your home line so data only goes through the eSIM. Answering calls on your home number abroad may still incur roaming charges under your carrier's plan.

You can delete it in your phone's settings once the plan has ended. Don't delete it while the plan is still valid; a deleted eSIM usually can't be reinstalled.

An eSIM is a digital product issued immediately after payment, so the 7-day right of withdrawal doesn't apply. Plans marked "Refundable if not installed" can be fully refunded within 30 days of purchase if not yet installed; other plans can't be refunded once the installation details are sent. If you still can't connect after help from support because of a network problem, any plan can be refunded. See our refund policy.
