Before you start

Original passport for SIM registration — this is a legal requirement, not a formality
An unlocked handset, or an eSIM-capable one if you want to arrive connected
For home fibre, a tenancy agreement and the landlord's written consent to any fixed installation

Step-by-step

1
Buy and register a prepaid SIM on arrival
Operator counters at Penang International Airport and in the island's malls will sell and register a SIM in minutes against your passport. Registration is mandatory under MCMC rules; an unregistered SIM gets cut off. Buy from an official operator store rather than a general shop so it is registered correctly the first time.

2
Move to a monthly prepaid or postpaid plan once settled
Monthly prepaid plans are inexpensive and require nothing beyond the registered SIM. Postpaid gives larger allowances and easier handset deals but needs a local address and a valid pass. If you will rely on Malaysian bank one-time passwords, a properly registered local number matters — foreign or short-term tourist SIMs sometimes fail bank verification.

3
Check what fibre the building already has before you sign a lease
Ask the landlord or building management which provider is physically cabled to the unit. Modern Penang condominiums are usually pre-wired and switching provider may simply not be possible; older houses and shophouses may need a fresh drop. Ordering the wrong provider means a cancelled installation and a wasted fortnight. This question belongs in the viewing, not after signing.

Order home fibre and allow for installation lead time
Unifi (Telekom Malaysia), Maxis Fibre and Time are the main options depending on what reaches your building. Plans span a wide speed range at prices that are low by Western standards. Installation typically takes a few business days to a couple of weeks. Many furnished rentals in Penang come with an existing subscription in the landlord's name — check whether you are taking it over or ordering fresh.

In the heritage zone, treat fibre as a building question and get consent in writing
Inside the George Town UNESCO core and buffer zones, alterations to a building's external fabric are controlled under the Special Area Plan and require the local authority's heritage approval. That constrains where cables can be fixed and how they can be run. In practice landlords of heritage shophouses either already have a working line or have a reason they do not. Get the answer, and any consent to install, in writing before you commit to working from home there.

Things most newcomers don’t know

Fibre in a George Town heritage shophouse is a conservation question before it is a telecoms one.

Buildings inside the UNESCO core and buffer zones are governed by the George Town Special Area Plan, which controls alterations to the external fabric — façades, rooflines and fixings included. That is not an obstacle a technician resolves on the day; it is the reason some beautiful shophouses simply do not have a good line and the landlord has stopped trying. Anyone planning to work from a heritage address should confirm the existing connection works, at the speed advertised, during the viewing.

A tourist SIM and a properly registered local number are not interchangeable for banking.

Malaysian banks send one-time passwords to a Malaysian number and their systems are sensitive to how the SIM was registered. People who arrive on a short-term tourist pack and then try to activate mobile banking sometimes find verification failing for reasons no one at the counter can explain. Registering a standard prepaid SIM against your passport, at an official store, avoids the problem entirely.

Ask which provider is cabled to the unit, not which provider is best.

In Malaysian condominiums the building's existing infrastructure usually determines your options, and a developer may have an arrangement with a single provider. Choosing a plan first and discovering the building cannot take it is a common and entirely avoidable fortnight of delay. The question takes ten seconds at the viewing and saves the whole problem.

Coverage on the island is strong; the useful question is indoor coverage in your specific block.

All three main operators cover urban Penang well on paper, but building materials, floor height and orientation change what you actually get inside a unit — older concrete blocks and heritage buildings with thick walls are the weak spots. Run a speed test standing in the actual room you would work in during the viewing, on the network you plan to use, rather than trusting the coverage map.

Common mistakes to avoid

Bringing a photocopy of your passport rather than the original to register a SIM
Signing a heritage-shophouse lease on the assumption that fibre can simply be installed afterwards
Ordering a fibre provider that is not physically cabled to your building and losing the installation slot
Relying on a short-term tourist SIM for Malaysian bank one-time passwords
Not testing mobile signal inside the actual unit during the viewing, especially in thick-walled older buildings
