Portable WiFi Malaysia 2026: Which SIM, Cost per GB

RM0.99 per GB against RM0.14 per GB. The first figure is Malaysia's best-known portable WiFi plan, Yes Huddle XS at its largest tier. The second is a RM55 Hotlink prepaid pass dropped into a MiFi you own. Same job, same airwaves, seven times the price.

The device sold to you as "portable WiFi" is consistently the worst value per GB on the board. That is the finding, and it holds across all five Yes Huddle tiers, not just the flattering one.

Every option, side by side

Read on 21 September 2026 from hotlink.com.my, celcomdigi.com, unifi.com.my and yes.my. Cost per GB is our own arithmetic, explained in the next section. Yes prices exclude SST until checkout, by its own note.

Buying the hardware outright is what makes the RM0.14 per GB column possible, because it removes the contract from the equation. We do not quote a device price here: Shopee's listings would not load for us without a login, and a price we have not seen is a price we will not print.

Working out what a gigabyte actually costs

Every figure in this column is ours, calculated as the monthly price divided by the full published quota. That scenario matters: it is the best case, the price you pay per GB only if you consume the entire allowance every month. Use half and the real cost per GB doubles.

Unifi Air's two unlimited tiers are missing from this table on purpose. Unifi sells Unlimited 5G at RM99 and RM149 a month, and its own plan card states that a fair usage policy applies to the RM99 tier without publishing the quota. You cannot compute a cost per GB from an undisclosed denominator, so we have not invented one.

If you want phone plans ranked as phone plans, including how each one treats tethering, that lives in our best prepaid plan comparison. This page is only about what happens when the SIM leaves the phone.

A one-off device purchase plus a RM55 prepaid pass is the combination that produced the cheapest per-GB figure on this page. Check the band support against your operator before buying any unit.

The clause nobody quotes before selling you a MiFi

Here is the question every listicle skips: does your operator's contract actually permit its prepaid SIM to live in a router? We read the published terms rather than the marketing pages, and the three operators do three different things.

CelcomDigi names it directly

CelcomDigi's published prepaid terms, in the clause governing standard usage, read:

Read that in context before you panic. The clause sits inside a section about calls and texts, the rest of its list is call-centre and bulk-messaging abuse, and the stated consequence is pay-per-use call rates rather than disconnection. CelcomDigi also sells Hotspot as a headline feature on every prepaid plan it lists. So the fair summary is not "CelcomDigi bans MiFi use". It is that the operator has written the phrase "using your SIM card in any other devices" into its own definition of non-standard usage, and has left itself room.

Hotlink says nothing at all

We searched the full Hotlink Prepaid 1.0 terms for the words tether, router, modem, MiFi, dongle and portable. All six appear zero times. What the document does contain is a table of eight internet passes with an explicit Hotspot column marked Yes on every row, alongside a requirement that passes are "strictly for personal usage only".

That silence is the honest answer for Hotlink: the contract neither permits nor forbids a router, it grants hotspot and restricts you to personal use. If you are running one household off it, you are inside the stated restriction. If you are reselling connectivity, you are not.

Unifi Air ships the MiFi itself

Unifi removes the question by supplying the hardware. Its RM99 and RM69 plans both offer a choice of a ZTE MC8810 5G router or a ZTE U30 5G Mi-Fi, free, on a 24 month contract. Unifi's own FAQ list includes the question "Can the device work if I change the SIM card?". We could not retrieve the answer, because the accordion did not expand for us and the linked terms PDF returned a 404 on the day we checked. We are not going to guess at it.

What the fair usage cap does once you share a connection

The quota follows the plan, not the phone. A 200GB fair usage allowance is still 200GB when the SIM sits in a MiFi. The difference is how quickly a shared connection eats it, because laptops, a TV and three phones consume at a rate one handset never will.

CelcomDigi publishes the consequence without euphemism: the fair usage quota is 20GB for weekly passes and 200GB for monthly passes, and "upon full utilisation of the FUP, the speed will be reduced to 512kbps until the Internet Pass expires". That is not a slowdown you work through. It is the end of useful service until the month turns.

Speed caps matter more than quota for most people. Hotlink's RM30 pass is capped at 18Mbps and its RM40 pass at 48Mbps, with uncapped 5G only between 8pm and 8am. A 50GB allowance you can never draw faster than 18Mbps behaves very differently from 50GB at full speed, and that distinction disappears from every comparison table that lists quota alone.

For a fixed connection at a fixed address, a 5G home router is usually the better instrument than a MiFi, and we compare those separately in the best broadband plan guide.

The SIM in the drawer that quietly dies

A MiFi is the classic way to lose a phone number, because the SIM inside it is out of sight and nothing prompts you to reload it.

CelcomDigi's lifecycle is explicit. Validity extends with each reload, then the account enters a 60 day grace period on expiry, during which you can receive calls and SMS but cannot use data. Miss the end of it and the plan is terminated, unused credit is forfeited, and in the operator's own words "the prepaid account number (MSISDN) will be recycled upon termination". Hotlink runs the same structure on a 50 day credit grace period, ending in termination and forfeiture.

The practical fix is dull and it works: put the MiFi's reload date in your calendar, not in your memory, and keep the number on a small recurring pass rather than letting it lapse between trips.

Battery, heat and how many people can actually connect

Operators publish device claims; manufacturers publish spec sheets; the two do not always meet. Yes states an 8 hour battery for the Huddle XS modem and support for up to 10 simultaneous Wi-Fi devices. Unifi rates its bundles by household size rather than by hardware: up to 3 users on the RM69 plan, up to 5 on RM99, and up to 10 on the RM149 router plan.

For the ZTE U30 that Unifi ships, we could not find a manufacturer spec sheet published for the Malaysian market. Retailer listings for U30 variants disagree with each other, quoting anywhere from 3,500mAh to 5,000mAh and 20 to 32 connected devices. Those numbers are not reliable enough to print as fact, so treat Unifi's per-plan user guidance as the figure that is actually contractual.

When your phone is already the right answer

Most people asking this question do not need a second device. If your current plan includes hotspot, tethering costs you nothing extra, and you are carrying one gadget and one charger instead of two.

A separate MiFi earns its place in three specific situations. When several people need a connection and you would rather not spend your phone's battery on it. When you want a network that stays in one place (a rental, a site office, a room) while people come and go. And when the connection has to keep running after you and your phone walk out.

Outside those three, buying a MiFi means paying for hardware, a second line and a second reload date to replicate something already in your pocket.

Reader context, and we are labelling it honestly: the pocket WiFi question recurs on r/malaysia across years rather than in a current thread. Searching the subreddit on 21 September 2026 surfaced "Pocket wifi rental recommendation?" from about four years ago with 25 comments, "Best Pocket Wifi To Rent?" from roughly seven years ago, "Best no contract wifi packages?" from about five years ago, and "Best SIM/broadband provider" from around a year ago. We could not open the thread bodies, because Reddit served an age-gate interstitial, so we are citing their existence and recurrence, not paraphrasing comments we did not read.

The verdict

Choose Unifi Air 120GB at RM69 instead if you would rather not buy hardware and the 24 month contract does not bother you. RM0.58 per GB is four times the prepaid rate, and the free ZTE U30 is what you are buying with the difference.

Choose Yes Huddle XS only if coverage at your address favours Yes or you specifically want a bundled LTE modem on a shorter 12 month term. At RM0.90 to RM1.00 per GB it is the most expensive data on this page, and it is LTE rather than 5G.

Choose your phone's hotspot, which is to say choose nothing, if you are one or two people who need a connection occasionally. That covers more readers than the other three combined.

Owning the device is the whole basis of the recommendation above, because it is what lets you pay RM0.14 per GB on a no-contract pass instead of RM0.90 on a twelve-month one. Check 4G and 5G band support for your operator on any listing before buying.
