BLIVALE Customer Support: a real eSIM support case for China and Hong Kong

At BLIVALE, customer support never goes through a bot. Every request - by email or WhatsApp - is handled by a real person, who follows the customer step by step until the issue is solved. In this article we share a concrete case: two China Unlimited eSIMs activated by the same customer, the issues she ran into, and how we solved them in real time.

Why our support makes the difference

Direct reply from an operator, never an automated chatbot
Support via email and WhatsApp, in the customer's own language
Real-time check of the eSIM status (installation, data usage, coverage)
Step-by-step guidance even through the most complex procedures, such as the real-name registration required by some local carriers

The case: two China Unlimited eSIMs for the same trip

The customer initially purchased an eSIM CHINA - Unlimited Data - No Roaming Charges, No Speed Limits: 10 Days and, later on, a second eSIM to extend coverage to Hong Kong and Macau as well: eSIM CHINA - HONG KONG - MACAU - Unlimited Data - No Roaming Charges, No Speed Limits. During the trip, two separate support requests came up, both resolved on the same day.

1. Data speed seemed to have slowed down

Hi! My data has seem to be slower down?07:01

BLIVALE SupportDear [Customer], We are currently running some checks. In the meantime, we are attaching an image showing part of the data traffic you have used since 16/09/2026: 21,871.54 MB (approximately 21 GB). Which city or area in China are you currently in?07:11

Thank you! I am in Guilin right now, Yangshuo07:16

Check APN, send us the screenshot.07:23

How do I check that?07:25

Please change "cmlink" to "cmhk". No need input for Username and Password07:48

Ok! Thank you!07:56

Within minutes we identified the cause: a sub-optimally configured APN. The fix (from cmlink to cmhk) instantly restored full speed.

2. The Hong Kong eSIM wasn't working after installation

I also just installed the Hong Kong e sim but it doesn't seem to work? Can I get some assistance regarding that?11:14

BLIVALE SupportDear [Customer], We have looked into this for you. For Hong Kong - and specifically for this type of eSIM - it is necessary to complete real-name authentication, as outlined in the documentation provided.11:20

You also need to fill in the details as shown in the image: select Hong Kong, enter email address, enter ICCID, select and enter Passport details, and select all the required options as shown in the second image.11:37

That's done! So it should work now? I appreciate the assistance!11:39

What "Real-Name" registration is, and why it's sometimes required

BLIVALE almost never asks its customers for an identity document: when we do, it's only to confirm that the order genuinely comes from its owner. For some destinations, however - such as Hong Kong and Taiwan - the local carrier requires, by law, a real-name registration of the eSIM, entering the ICCID and an identity document directly on the carrier's portal. This is a standard procedure of the local market, not a BLIVALE policy, and in our experience customers have never had trouble completing it by following our step-by-step instructions.

Before the support case: an order followed from start to finish

Support didn't stop at solving the two technical issues. The BLIVALE team also followed the customer through the purchase and shipping stages: order verification, email confirmation, payment handling via instant SEPA transfer for one of the eSIMs (South Korea), and clear communication on activation timing.

BLIVALE SupportWe have shipped the first two orders paid via Stripe. Please note that you have 55 days to activate the QR code and, consequently, the eSIM. Install the eSIM only when you need it; you will need an internet connection (Wi-Fi or other) to do so.10:05

Thank you very much!! I appreciate it!10:07

Note: not every customer has prior experience with eSIMs. Even though every order comes with written installation instructions, our team remains available to answer any question, quickly.
