Yes 4G/5G SIM Review 2026: Malaysia's 5G Pioneer, from RM30

What Yes Is & Its 5G History

Yes is a Malaysian mobile network operated by YTL Communications, part of the YTL Corporation group. It launched in 2010 as a data-first, all-IP operator — at the time an unusual, internet-native approach in a voice-centric market. That heritage is why Yes has always leaned into data and, later, 5G rather than traditional voice bundles.

When Malaysia rolled out 5G through Digital Nasional Berhad (DNB) — the government-linked entity that built the country's initial single 5G wholesale network — YTL was among DNB's shareholders. That gave Yes an early and visible role in the 5G era, and the brand has marketed itself heavily as a 5G-forward operator. (Malaysia has since moved toward a dual-network 5G model; the precise wholesale arrangements have evolved, so we'd frame Yes as an early 5G mover rather than the sole 5G player.)

Today Yes sells both 4G and 5G prepaid and postpaid plans, plus portable Wi-Fi / data devices. For this review we focus on the prepaid 4G/5G SIM most people buy on Shopee — what you get, how the 5G holds up, and where the honest trade-offs are.

Plans, Data, Validity & Price

Yes prepaid bundles commonly start from around RM30, and the brand is positioned around generous data rather than micro starter plans. Because Yes refreshes its line-up regularly, the table below is a general guide — confirm the exact quota, validity and any fair-usage terms on the specific listing before buying.

Unlimited-Data Offerings Explained

A big part of Yes's appeal is its unlimited-data positioning — both on SIM plans and on its portable Wi-Fi / home data devices. For a city-based heavy streamer, gamer or remote worker, an unlimited-style Yes plan can be one of the better data-per-ringgit deals in Malaysia.

The honest caveat, as with virtually all "unlimited" mobile plans here, is the fine print. Depending on the specific plan you may encounter:

• Fair-usage policy (FUP): speeds may be managed after a high usage threshold.
• Hotspot caps: tethering data is sometimes limited separately from on-device data.
• Speed tiers: some plans cap maximum speed rather than total data.

None of that makes the plans bad — it just means "unlimited" is best read as "very generous data, subject to terms." If you plan to tether a laptop all day or replace home broadband, read the FUP and hotspot conditions on the exact plan first.

5G Coverage, Strengths & Weaknesses

This is where being honest matters most. Yes's strength is urban 5G and data value; its weakness is overall coverage breadth.

For context: CelcomDigi is widely regarded as having Malaysia's broadest coverage (especially rural and Borneo), with Maxis close behind. Yes generally sits below the big two on overall reach, which is the main reason it is better suited as a city-centric primary SIM or a secondary/data SIM than as a do-everything national SIM.

The practical advice: check Yes coverage (and 5G availability) for your specific home, work and travel spots before committing. If those locations are well covered, Yes can genuinely outperform on value; if you roam widely or rural, lean toward CelcomDigi or Maxis instead.

Where to Buy, Registration, eSIM & Hotspot

Where to buy. Yes SIMs are sold on Shopee, the Yes website and app, Yes stores/kiosks, and selected retailers. Shopee is the easiest way to compare the current data bundles and pick one up before or shortly after arriving.

Registration. All prepaid SIMs in Malaysia must be registered under MCMC rules — Malaysians use a MyKad, foreign visitors use a passport. Registration is usually handled in the Yes app or at point of sale; keep your ID ready when activating.

eSIM. Yes has offered eSIM on compatible phones, activated by scanning a QR code instead of inserting a physical card. eSIM support isn't guaranteed on every plan/listing, so confirm it (and that your phone is eSIM-compatible) before buying if you need a digital SIM.

Hotspot / tethering. Yes plans generally allow hotspot use — and Yes is well known for portable Wi-Fi devices — but some plans cap hotspot data separately or apply a fair-usage policy. If tethering is central to your use, verify the hotspot allowance on the specific plan.

Yes vs CelcomDigi, Maxis, U Mobile & eSIMs

Yes competes against Malaysia's big networks (CelcomDigi, Maxis/Hotlink), the budget challenger (U Mobile), and travel eSIMs (Airalo, Yesim) that don't need a physical SIM at all. The right pick depends on whether you prioritise coverage, price, data volume or convenience.

vs CelcomDigi: CelcomDigi wins on raw coverage, which is the single biggest reason to prefer it for travel, rural trips or Borneo. Yes counters on 5G-forward branding and data value in cities. If reliability everywhere matters most, CelcomDigi; if you're city-based and data-hungry, Yes is the value play.

vs Maxis / Hotlink: Maxis offers a strong balance of urban and rural coverage and a popular multi-country travel SIM (Hotlink). Yes can undercut on data value in well-covered areas but doesn't match Maxis's breadth. Pick Maxis/Hotlink for a dependable all-rounder, Yes for city data value.

vs U Mobile: U Mobile is the budget challenger with the cheapest entry tourist/data plans and good urban performance, but weaker rural reach. Both Yes and U Mobile are city-strong value picks — choose based on the exact plan price/data and which has better coverage at your locations.

vs travel eSIMs (Airalo, Yesim): for short visits, a travel eSIM is the most convenient option — activate before you land, no physical SIM, often multi-country. The trade-off is they ride on local networks (so coverage mirrors whichever partner they use) and can cost more per GB than a local prepaid. For longer stays or heavy data, a local Yes/CelcomDigi/Maxis SIM is usually better value; for a quick, hassle-free trip, an eSIM wins on convenience.

Who Yes Is For (Audience Cohorts)

Yes fits some users far better than others. Here is how it lands across the main cohorts:

Setup Tips

1. 1Check coverage first. Before buying, confirm Yes (and 5G) coverage at your home, work and key travel spots — this is the single biggest factor in whether Yes works for you.
2. 2Read the plan fine print. Verify the data quota, validity in days, 5G eligibility, and any fair-usage / hotspot caps on the exact listing before paying.
3. 3Have your ID ready. MCMC registration is mandatory — MyKad for Malaysians, passport for visitors. Register via the Yes app or at point of sale.
4. 4Want eSIM? Confirm your phone is eSIM-compatible and that the specific plan supports eSIM before purchasing.
5. 5Consider Yes as a second SIM. Pairing a coverage-first main SIM with a cheap data-heavy Yes SIM (or portable Wi-Fi) often gives the best of both worlds.

Pros and Cons

FAQ

Final Verdict: 4.0/5

Yes is a genuinely good prepaid SIM for the right user. Its 5G-forward heritage, data-heavy plans and value pricing (from around RM30) make it one of the better picks for city-based, data-hungry users in areas where Yes coverage — ideally 5G — is strong. As a cheap secondary or data-only SIM, it's especially easy to recommend.

The honest limitation is coverage. Yes generally trails CelcomDigi and Maxis on overall reach, particularly in rural areas and East Malaysia, and its "unlimited" plans can carry fair-usage and hotspot conditions. That keeps it from being a no-questions national SIM, and is why we land at 4.0/5 rather than higher.

Bottom line: if you're city-centric and want lots of fast data for the money, check Yes coverage at your locations and it can be excellent value. If you travel widely or rural — or you're a tourist heading beyond the big cities — CelcomDigi or Maxis/Hotlink (or a travel eSIM for short trips) is the safer call.
