worst customer service ever

worst customer service ever! I ordered the card and they told me I would be able to transfer my number - after the card arrived they told me it is not possible. Talking to agents takes hours or days and they have no idea what they are talking about!! Absolute nightmare!!!

My CMLink experience

I ported my number over from S***** to CMLINK and have been using their 5G+ plan. So far, I’ve had a positive experience.

For the price, CMLINK’s network coverage and stability are surprisingly good. I haven’t encountered any major connectivity issues, and the service has been reliable for my daily use.

Their customer service is also commendable. Although the support staff aren’t always fluent in English, they genuinely try to be professional, patient, and helpful in resolving my issues.

One feature I really appreciate is that CMLINK automatically upgrades your plan when they introduce better promotional packages, so existing customers aren’t left paying more for less. That’s a customer-friendly approach that not many telcos offer.

Overall, CMLINK offers excellent value for money. If you’re looking for an affordable telco with good coverage, stable performance, and fair treatment of existing customers, I’d definitely recommend giving them a try.

Customer service is shitty

Customer service is shitty. They don't have any at all. They just dragging the time so that the chat will be expired and passed on to the next agent.

Hopeless! DON'T use them NOT RECOMMENDED!!!!!

Unfair replacement charges for loyal customers

have been a customer of CMLink for over two years, but I’m very disappointed with their policy on SIM replacements.

Every time I need a SIM replacement, whether it’s an eSIM or a physical SIM card, I am charged £3. This applies every single time, without exception. In comparison, most other mobile providers do not charge for replacements, or at least offer it free under reasonable circumstances.

As a long-term customer, this feels unfair and frustrating. It gives the impression that customer experience is not a priority, and there is little consideration for loyalty or convenience.

Overall, this policy is not customer-friendly and makes the service feel less competitive. I hope they reconsider this approach and improve their support for existing users.

Can not ring abroad from China

I am in China but unable to make any calls I needed to telephone someone in the United Kingdom urgently but unable to make any outgoing calls online chat support useless, also email support useless I had to buy Chinese SIM to be able to make calls back to the United Kingdom. Avoid this company it doesn't do what's on the tin, what's the point in this SIM if you can't ring abroad from china and support is useless.

Spam calls, bad signal, cut off you mobile data without inform you

Spam calls, signal is really bad, no sim card error, trying to use esim but won't send activation link for 2 days and cut off my sim card mobil data, when link came it can not be activated, spent another 3 days to fix this, put me 1 week without mobile data.
It's price is not competetive either, Smarty offer similar price contract, would avoid with any cost.

A true (very bad) experience of Chinese business practices

Very poor overall.

I have a unique perspective as I'm British, but travel to China a lot

With CMLink you get to experience an authentic awful Chinese customer service and business practices.

Here's an example - say you run out of data mid package. You can't just renew it or buy another you must wait till the old useless package expires and they try to force you to buying stupidly priced add-ons. Customer service won't help either... It's beyond stupid.

Oh and you'll start getting Chinese spam calls after signing up... Perhaps Chinese customers wouldn't think much of it, but as a British person I know 100% CMLink has sold my number.

Awful all around

It's hard to complain when the prices are so low but the service us mediocre.
I'm not talking about slow download speeds because they're to be expected for the price point but the coverage and signal stability are abysmal as well which should not be the case.

SCAM ALERT

Do NOT every get any product or service from China Mobile. This is a complete SCAM company.
I bought a visitor SIM for Hong Kong AT THE AIRPORT from them and they told me it also covers mainland and Macao inclusive in the plan, but it does NOT.
Instead, your money disappears and you are left with no data...

Not recommend

I bought two SIM cards for traveling in Italy and France. It worked well in Italy but not France. The internet connection shutdown suddenly on the second day in France. The contact between customers services took a lot time and not helpful. They kept repeating their manual. Do not recommend.

OK a few niggles

The price isn't great, get a number ported ASAP as you will get a lot of scam Chinese calls from the cmlink number.
The company is aimed at Chinese languages, however I use the company as it has great roaming for places like Turkey.

the company is not capable to do properly the port of your existing mobile phone No (after 2 days still not working).

I think the support is mainly working on Chinese hours, so not very helpful when you have an issue.

There is a very strange transfer message when you try to make a call to your No ("Call being transfered" !!!!), i m very suspicious about the safety.
