Quick answer
Malacca and Johor Bahru are places named for this Malaysia eSIM. The same U Mobile 4G line covers both. Turn on Data Roaming for the eSIM, keep it off on your home SIM, and choose a plan long enough for the whole trip.
Can one eSIM cover Malacca and Johor Bahru?
Yes. You install one Malaysia eSIM and use it in both places. It is data only, with no phone number and no documents. There are no top-ups, so buy enough days before you start.
What do I need the data for?
Maps, Grab rides, and WhatsApp. WhatsApp calls work over this data. Hotspot is included. TikTok and most AI apps, such as ChatGPT, do not work on this eSIM.
Which plan suits these stops?
For two weeks or more, choose 15 days · 10 GB or 20 GB, or 30 days · 20 GB. For about a week, choose 7 days · 5 GB or 10 GB, or 7 days · Unlimited for heavy use. Add one day: each plan day is a rolling 24 hours from install, not a midnight reset.
Frequently asked questions
Do I need a new eSIM when I leave Kuala Lumpur?
+
No. The same eSIM is for Kuala Lumpur, Malacca, and Johor Bahru. You only need a new plan when the current one runs out of days or data.
What if I run out of data?
+
There are no top-ups. Buy a new plan. It comes with a new QR that you install as another eSIM.
When do the days start?
+
Days start once the eSIM is installed. Each day lasts 24 hours from that point. Pick one day more than your stay.
