How to switch home internet ISP without downtime: steps, channels and equipment (2026)
Decision details
Fits if: Households switching between unifi, Maxis, TIME, U Home or other providers, including those burned by stalled port-overs.
Main drawback: Processes and installation slots vary by address and account; these steps are a control sequence, not a timing guarantee.
Compare: new-address coverage; old line stays live; application channel; equipment compatibility; written termination confirmation; final bill.

How to switch ISP without dropping your line
[Reviewed: 10 October 2026]
Short answer: do not close the old account first. Check the new provider’s coverage at your full address, apply for the new service, keep the old line alive until the new service actually works, then close the old account with written confirmation — termination date, final bill and equipment return instructions. Malaysian community threads repeatedly describe switches stuck in limbo because the old line was terminated too early; this sequence avoids that failure mode.
Six controlled steps
- Check the target provider’s coverage at your full address (building name for high-rises). Coverage beats price — the recurring community decision rule is to pick by availability at your address, not brand speed claims. A checker result is not an installation guarantee; have the provider confirm port and slot. [source]
- Check the old account’s contract status — remaining months and any early-termination charges. If the term is long, price the switch with those charges included (see the contract-expiry guide).
- Apply for the new service without cancelling the old line. State your preferred installation date and get an application reference number. For high-rises, give the exact building name.
- Allow a short overlap. Keep the old line active until the new installation is tested at home (speed and a video call in the evening, not just midday).
- Close the old account in writing — ask for the effective termination date, the final (prorated) bill, deposit status and equipment return instructions. Do not hand over equipment without a receipt.
- Keep every record — application references, screenshots of the offer, termination confirmations. If bills keep arriving after termination (a recurring community complaint), your paper trail is the basis of the dispute.
Choosing a channel: walk-in, app, or agent
| Channel | Strength | What to secure |
|---|---|---|
| Provider store walk-in | Documents checked on the spot; written receipt | Bring your IC; if the account is in another name, bring authorisation/transfer documents |
| Official app/portal | Digital record; official printed offers | Save the reference number; check the checkout price, not the ad |
| Agent/reseller | Sometimes smoother paperwork | Get terms in writing on letterhead or an official message; record promised gifts |
The recurring community complaint: agent-promised gifts or rebates never arrive after installation, and the customer has no record to claim with. Practical rule: whatever is load-bearing (monthly price, contract length, charges) must sit on an official provider document — an agent’s gift is a bonus and should never be the main reason to switch. A class of agent offers quoting far below official print exists and recurs; numbers in that class are unverified. [source]
Equipment: the question everyone misses
Community experience shows devices (routers/ONTs) from a previous provider are sometimes locked to that provider’s configuration and will not work with the new one, even when they power on. Three questions before switch day:
- Is the old device mine, or the old provider’s (rented/loaned)?
- What device does the new provider supply, and is it included in the monthly price?
- If I own a router, does the new provider support using it (and what settings does it need)?
Get the answers in writing. If you must buy a new device, add that cost to the switch comparison.
Re-check pricing and terms on switch day
Prices move; these are dated reads for reference (unifi/Maxis 2 Oct 2026; TIME 4 Oct 2026): unifi 100Mbps RM89 promo/RM99 RRP and 500Mbps RM149/RM159 on a 24-month minimum [source]; Maxis 100Mbps RM89 for the first 24 months/RM99 and 500Mbps RM149/RM159 on a 24-month commitment [source]; TIME 24-month 200Mbps RM99 and 600Mbps RM99 for six months then RM139, with 12-month and no-contract options (one-time fees RM400–RM800) if you want to stay easy to leave after switching. [source] [source]
Per-row consequence over those dated reads — 24-month totals (our arithmetic, before tax):
| Plan (dated read) | Recorded monthly price | 24-month total (our arithmetic) | Suits |
|---|---|---|---|
| unifi 100Mbps, 24-month contract [source] | RM89 promo / RM99 RRP | 24 × RM99 = RM2,376 (at RRP; promo duration not printed) | most homes staying the full 24 months |
| Maxis 100Mbps, 24-month commitment [source] | RM89 first 24 months / RM99 RRP | 24 × RM99 = RM2,376 (price after the promo period) | most homes staying the full 24 months |
| TIME 200Mbps, 24-month contract [source] | RM99 | 24 × RM99 = RM2,376 | moderate use, flat price from day one |
| TIME 600Mbps, 24-month contract [source] | RM99 first 6 months, then RM139 | 6 × RM99 + 18 × RM139 = RM3,096 | heavier use on an intro price |
| TIME 200Mbps, no contract [source] [source] | RM99 + RM400 once | 24 × RM99 + RM400 = RM2,776 | anyone who may move — easy to leave any month |
If your switch stalls (the port-over never completes, the new line never activates), do not pay duplicate months without a record: request written status from both providers, keep dates, and if nothing resolves, a consumer-regulator (MCMC) complaint is the escalation route communities use — with written evidence, the complaint carries weight.
For switch enquiries, share your current provider, target provider and general area on WhatsApp; the operations team routes it to a relevant ISP dealer for confirmation of coverage, current pricing and installation sequencing. [source] Your enquiry moves through a registered dealer channel — what comes back is written confirmation of coverage, pricing and terms for your address, not a promised date. Enquiries are answered by a human during working hours; we do not promise SLAs we do not measure.
Check my plan options (WhatsApp): current provider/plan, contract-end month, general area.

Frequently asked questions
Should I terminate my old internet before applying for the new one?
No — unless you can tolerate days to weeks offline. The safe route: apply for the new service, keep the old line active until the new one works, then close the old account in writing.
How do I avoid downtime when switching ISP?
Plan an overlap: keep the old line until the new installation is done. Use mobile data or hotspot as a backup in between. Do not return the old equipment until the new service is live.
Is a Facebook agent or a walk-in store safer for switching?
Both can work. Whichever channel you use, get an application reference number and a copy of the terms. Keep the agent's promises (price, gift, dates) in writing; verbal promises are hard to claim after installation.
Can I reuse my old router with the new provider?
Verify in writing with the new provider. Community experience shows devices from another provider are sometimes locked to its old settings and will not work; assume you need new equipment until confirmed otherwise.
