About China Mobile Hong Kong

China Mobile Hong Kong (CMHK) is a telecommunications company providing mobile voice, data, roaming, broadband, and value‑added services to customers in Hong Kong. It operates as the Hong Kong arm of China Mobile, one of the world’s largest mobile network operators, and markets a range of prepaid and postpaid plans, roaming packages covering Mainland China and other regions, and various digital services for both consumers and businesses.([zh.wikipedia.org](https://zh.wikipedia.org/wiki/%E4%B8%AD%E5%9C%8B%E7%A7%BB%E5%8B%95%E9%A6%99%E6%B8%AF?utm_source=openai))

A charge with a descriptor similar to “Y47G 13800138000 HK” likely relates to mobile service or top‑up for a China Mobile / CMHK number, as 13800138000 is widely used as a China Mobile recharge and service number and the “HK” suffix typically indicates Hong Kong processing. This type of charge may come from paying a postpaid mobile bill, topping up a prepaid SIM, paying roaming/data package fees, or settling IDD/roaming usage linked to a CMHK or China Mobile account, often processed through an online payment portal or automatic card debit.([china-mobile-phones.com](https://www.china-mobile-phones.com/how-to-use-a-china-mobile-recharge-card.html?utm_source=openai))

If you are unsure about the charge, the safest steps are to log into your China Mobile Hong Kong account or app to review recent bills, top‑ups, and value‑added service purchases, and to match the date and amount with line‑item details. You can also contact CMHK customer service using the official hotline or contact details on their website, rather than any number in a suspicious text or email. If you still cannot match the transaction, ask your card issuer to confirm merchant details, dispute unfamiliar charges, and, if necessary, replace your card to prevent further unauthorized use.

Frequently Asked Questions

Why do I see a charge related to 13800138000 with an “HK” suffix on my card statement?

The number 13800138000 is commonly used as a China Mobile recharge/service number, and when paired with an “HK” suffix it often indicates a payment processed for China Mobile Hong Kong or a related China Mobile service billed through Hong Kong. This can reflect a mobile bill payment, prepaid top‑up, or roaming/IDD fees charged to your card.

What types of services from China Mobile Hong Kong typically result in card charges?

Typical card charges arise from monthly postpaid mobile plans, broadband or bundled plans, prepaid top‑ups purchased online or in‑app, roaming and IDD add‑on packages, and occasionally device or SIM purchases where you authorize payment by credit or debit card.

How can I confirm which China Mobile Hong Kong line or service this charge belongs to?

Log into your CMHK online account or mobile app and review billing history for each mobile number or broadband account you manage. Match the transaction date and amount on your card with the corresponding invoice, top‑up, or package purchase listed in your CMHK account records.

How do I cancel or change a recurring China Mobile Hong Kong payment on my card?

If you set up auto‑pay with your card for a CMHK postpaid plan, sign in to your CMHK account or contact customer service to disable or update the auto‑pay arrangement. Once auto‑pay is turned off within CMHK’s system, future recurring card debits should stop after the current billing cycle is settled.

How can I request a refund or adjustment for a China Mobile Hong Kong charge I don’t recognize?

First, contact China Mobile Hong Kong customer service with your mobile number, account details, and a screenshot or copy of the card transaction so they can check their billing records. If CMHK confirms an error, they can arrange a credit or adjustment; if they cannot locate the charge, you should then open a dispute with your card issuer.

Could this CMHK‑related charge be a one‑time authorization hold?

When you add a card to your CMHK account or make a new online payment, the payment processor may place a small temporary authorization hold to verify the card. These holds usually disappear within a few business days and may not correspond to an actual billed amount on your CMHK invoice.

How do I contact China Mobile Hong Kong about a billing issue?

Use the official contact channels listed on hk.chinamobile.com—such as their customer service hotline or online support forms—to inquire about the charge. Have your CMHK account number, mobile number, billing address, and the exact transaction amount and date from your card statement ready to speed up the investigation.

What should I do if I don’t have any China Mobile or CMHK services but see this charge?

If you have never used China Mobile or CMHK and cannot link the transaction to any family member’s line, it may be a case of card misuse. Immediately contact your card issuer to report the unknown charge, request details of the merchant, dispute the transaction, and consider cancelling and reissuing your card to prevent further unauthorized activity.
