how much is the data rate there?

I was in an identical situation as you: on Hotlink, roaming package was shit compared to wife's Digi/Celcom.

So I took the plunge with [Link:Trip.com's eSim] after reading about it on the message boards with an Alien logo.

The prices seems too good to be true. The similar package as you described above is only less than RM15 !

But it worked perfectly for me. I bought the 10 days - Total 20gb package and still cost less than Hotlink's roaming.

I used it in Hangzhou, Wuzhen and Shanghai. Can access all our usual apps, and also Alipay, Dianping, Gaode maps, etc etc.

Highly recommended.

True that. As I said, Gaode 搞得 Map, a.k.a. Amap.

Doesn't hurt to call up the bank and tell them you are travelling.
It actually depends on the bank I believe. My parent's CIMB couldn't work but UOB can. My Maybank's does work as well.

But better safe than sorry. Just let them know / activate in the app.

Should be fine after verification in Alipay. Just make sure the Credit Card is usable.

Thank for reply. Will bring some cash in case since i have friends in China to reload.

Try refer to this link on trip.com. Maybe it helps ?

Personally, just last December I did use Gaode with just logging in via WeChat without binding to a phone number, but.... I just tried to log out and log back in, and it asked for a Chinese phone number 

EDIT: FWIW, I could use Gaode/Amap without logging in. The navigation and searching seems to be still working. Only lacking would probably be the ehailing.

Apple Maps turns into Gaode or Amap when you enter China.

If you're frequent traveler to China can consider open bank account.
Malaysia passport open bank account 30 minutes.

Last 2 weeks my brother in law opened one in ICBC Shenzhen. 20 minutes. Need your TIN, address (just put hotel), passport and Chinese phone number.

Not all.
They actually rejected an angmo with tourist visa when we were there.
Also, my SG friend having hard time opening too.

ICBC.
He did manage to open with CCB at the end.

BoC for foreigners useless. They mention no debit card. Tried few branches same answer.

I got my Ugreen 25000 confiscated during departure. First day when the law was enacted. No choice - nothing much can be done. Even courier company also not accepting power bank.

Same. As long as you're in China all powerbanks need to be CCC certified.
Even flying back KUL from Shenzhen also need pass through security, where powerbank they'll check.

Don't have to discard. If you buy reputable powerbanks they should be CCC certified, so it's safe to carry.
Only those without CCC certification cannot.

Do you guys experience hotel at Shanghai shutting down central Aircon?

I went Shanghai on April and the hotel does not allow Aircon in the room and I was asked to open the window

try this

it has number, data and VPN(if you opt for the VPN)
you activate using an APP and inside the app, u can pay a small fee to retain the number forever
meaning you can reuse the sim card over and over again
