Ubigi eSIM not working? Check the balance, profile and APN

Open the Ubigi app or Ubigi self-care. Its terms say self-care remains accessible when the plan is exhausted or expired, even though ordinary internet access is suspended. That is useful for seeing whether you need more data rather than a settings change. It still requires a usable network connection; if the profile won't register at all, use working Wi-Fi.

Confirm three things: the plan covers your current country, time remains and its data allowance isn't exhausted. If you bought a new plan, make sure it is on the account and profile you're actually using. Reinstalling won't add a missing allowance or restart an expired plan.

1. Open SIM settings and enable the Ubigi line. On iPhone, start at Settings, Mobile Service or Mobile Data. Galaxy uses Settings, Connections, SIM manager; Pixel uses Settings, Network and internet, SIMs.
2. Select Ubigi for mobile data and disable automatic data switching. Follow its travel-line roaming instruction. Keep Australian-line data roaming off. If a roaming control is shared or unclear, temporarily switch the Australian line off for the test, recognising that its calls and SMS will be unavailable.
3. If manual APN entry is needed, use mbb on the Ubigi line. Ubigi's iPhone guide specifies it in Mobile Data, LTE Setup, MMS and Personal Hotspot APN fields where available. On Android, enter mbb in the APN field, save it and select that profile. If those fields are hidden, send support the screen rather than editing another SIM.
4. Toggle aeroplane mode briefly, turn it off and allow registration. Restart once if needed. Try LTE/4G temporarily if 5G won't register; that is a diagnostic step, not proof your handset never supports 5G with the service.
5. If manual network selection is required, ask Ubigi which network that order can use at your location. Don't assume every operator in the phone's scan is included.
6. Turn Wi-Fi off and open a small webpage. If it loads, confirm Ubigi remains the data line. Avoid a large speed test while investigating an allowance problem.

If only hotspot is greyed out or fails while phone data works, revisit the Personal Hotspot APN on iPhone. This is a different fault from the profile showing No Service.

Ubigi’s unlimited plans don’t all renew their faster data in the same way. Some give you a faster allowance for the whole plan; selected daily plans give you 5GB in each 24-hour period from activation. The described offers drop to 2Mbps after their faster allowance is used. Check your purchased plan in the account: a whole-plan limit won’t refill every morning, and a 24-hour reset isn’t necessarily midnight.

Read the plan details in the account and compare the stated allowance with recorded use. If the connection is slow below that threshold, tell support both figures and your location. Don't assume every seven-day Ubigi plan has the same limit or that every slowdown is fair use.

Ubigi's reinstallation guidance permits up to five reinstalls in total, subject to its profile/device conditions. Use the app's reinstallation route on working Wi-Fi. If the original handset is lost, the limit has been reached or the app fails, ask support to recover the account/profile arrangement before buying again.

Deleting an eSIM profile is different from deleting the Ubigi account. Keep the account and purchase history while resolving the issue. Reinstallation is a recovery option for an already missing profile, not a reason to delete a present one.

Use the Ubigi help centre and its customer-service form. Include the order/payment receipt, country and town, model/software, account balance and expiry, exact error, and screenshots of data selection and APN. Hide QR codes and unrelated personal details.

Ask: “Does this account have an active plan for this country, is the profile correctly provisioned, and which local network should it use?” If you're travelling immediately, save bookings and directions over Wi-Fi while waiting. We haven't tested a response time for your case.

For a refund, Ubigi's terms distinguish an unscanned preloaded QR order, a recharge already used and a proven Transatel technical issue. They require a payment receipt with the online request within 14 business days of purchase or the technical issue. Scanning, carrier lock and usage can affect eligibility; don't assume the technical-fault route is the same as changing your mind.
