How to choose a fibre internet plan for a small office or shop in Vietnam

Choosing an internet plan for a small office or shop differs from choosing one for your home in one key way: when the connection drops, you lose orders, client calls and camera footage, not just entertainment. This guide brings together what to check before signing a contract, drawing on providers' official pages, the press and community discussions. It does not rank providers, because real-world quality depends heavily on the infrastructure on your street and in your building.

Estimate the speed you actually need

Rather than buying the fastest plan available, add up what happens at the same time during your busiest hours:

• Video calls: Zoom's official guidance puts an HD group call at a few Mbps in each direction. Ten people on calls at once still use only a few dozen Mbps, but they need stable upload.
• Cloud apps (sales software, online accounting, email, Google Drive/OneDrive): traffic is usually light unless staff often upload large files such as videos, drawings or product photos.
• Remote camera viewing: each Full HD H.264 camera stream typically uses a few Mbps. If the owner watches several cameras at once on a phone, that traffic goes out through the shop's upload.
• POS terminals, printers, VoIP phones, IoT devices: little bandwidth, but they need a constant connection.

Some provider advice pages suggest that an office of fewer than 10 people doing basic work is fine at around 100 Mbps, and that you should allow two to three times more headroom once regular video calls, cameras and cloud sync are involved. Business fibre plans from all three major providers now start at a few hundred Mbps, so for a shop or an office under 20 people the headline speed is rarely the bottleneck. The bigger risks are usually indoor Wi‑Fi, upload capacity and stability when reaching overseas services.

Upload, international bandwidth and static IP

Upload. Many business fibre plans are advertised with equal upload and download speeds, but home plans are not always symmetrical. Ask about upload explicitly if you livestream sales, hold many video calls or back up data to the cloud.

International bandwidth. The speed on a plan is usually the domestic speed. Some business plan families (for example VNPT's higher-tier plans) state a guaranteed minimum international speed. This matters if you rely on services hosted abroad. Vietnamese media have repeatedly reported submarine cable faults that slow international access while domestic traffic stays normal. These incidents affect every provider, so do not expect any plan to be fully immune.

Static IP. Standard connections use a dynamic IP, which can change. You need a static IP if you want to reach a camera recorder remotely without going through the camera maker's cloud service, set up a VPN into the office, run an in-house server, or if a partner whitelists access by IP address. According to FPT Telecom's official page, some business plans (the "Biz Plus" variants) include a static IP and others can add one; VNPT also has plan families that include a static IP and a LAN IP block. If your shop only views cameras through the camera maker's app, you usually do not need a static IP yet.

Wi‑Fi, modem placement and included equipment

Many "slow internet" complaints are really weak Wi‑Fi rather than a poor line.

• Put the modem or main access point in a central spot, not inside a metal cabinet, behind the checkout counter or against a concrete wall.
• Multi-storey tube houses and partitioned offices: one router is often not enough. Add wired access points or a mesh Wi‑Fi system. FPT's advice page recommends mesh for offices with many rooms or thick walls.
• Separate guest and internal networks: customers should join their own network and must not see your POS, printers or camera recorder.
• Wire fixed devices: POS terminals, camera recorders and accounting PCs are more stable on an Ethernet cable.

Business plans usually come with a newer Wi‑Fi modem, and some add an extra access point or a load-balancing router (FPT Telecom's official page lists this for its Super Biz line). Ask whether the equipment is lent or given, and what must be returned if you cancel.

Repair commitments, contracts and promotions

Repair time. All three providers publish 24/7 support lines for business customers. Still, "24/7 support" is not a repair-time commitment. Ask for, and get written into the contract or an annex, the response time, the time for a technician to arrive, and whether any compensation applies after a long outage. Standard business fibre (FTTH) usually lacks the strict service-level guarantees of a leased line, which is the product meant for sites that cannot tolerate downtime.

A backup line. According to many posts on Vietnamese tech forums such as VOZ, small offices often add a second line from a different provider and use a load-balancing router, so one line can fail while the other keeps working. For small shops, a 4G/5G SIM hotspot as a fallback for the POS is another option the community often mentions.

Read the contract and promotions carefully. Before signing, ask:

1. How long the minimum term is, and the penalty for early termination or moving premises.
2. When promotions (free months, free installation, free equipment) apply, and whether they require prepayment.
3. What the regular charge will be once the promotion ends.
4. What happens if you move offices: can the service be relocated, and how long does it take.
5. Invoicing: which company details the e-invoice will carry, and whether the name and tax code are correct.

Installation steps and documents

Providers describe a broadly similar process:

1. Register via the website, hotline or a service office.
2. Infrastructure survey: the provider checks whether fibre and a free port are available in your area. Office buildings may only allow certain providers to run cables, so ask building management first.
3. Sign the contract, in person or electronically. FPT Telecom says it supports e-contracts.
4. Pay for the chosen billing period.
5. Installation and handover: the technician runs the cable, sets up the modem and tests the speed. According to FPT Telecom's official page, deployment usually takes a few business days depending on infrastructure.

Documents businesses are commonly asked for: a copy of the business registration certificate, the representative's ID, a letter of introduction or power of attorney if the signer is not the legal representative, and the company seal or a digital signature. Household businesses and individuals renting premises may be asked for other papers, such as the lease. Confirm the exact list with the provider.

At handover, check for yourself: run a speed test on a wired computer, walk around to check Wi‑Fi at the counter and meeting room, change the modem admin password, and note down the contract number and the fault-reporting hotline.

Comparing FPT Telecom, Viettel and VNPT neutrally

All three offer dedicated business fibre plans, tiered by speed, IP type (dynamic or static) and international commitment. Plan names and bundled items change often, so below are the points worth comparing, not a verdict on who is better:

• Infrastructure at your exact address: the most important factor. Ask neighbours or shops on the same street which provider they use and how it has been.
• What the plan includes: domestic speed, international commitment, static IP, bundled Wi‑Fi or load-balancing equipment.
• Support commitments: response time, fault-reporting channels, and whether business customers get a dedicated account contact.
• Contract terms: length, prepayment, termination penalty, relocation.

If your business depends heavily on the connection, two lines from two different providers are often worth more than hunting for the single "best" provider.

Frequently asked questions

How much internet speed does a small office need?

Add up what runs at the same time in your busiest hours: a few Mbps per person on video calls, a few Mbps per Full HD camera stream. Some provider advice pages suggest around 100 Mbps is fine for an office under 10 people doing basic work, with two to three times more headroom once video calls, cameras and cloud sync are regular.

When do I need a static IP?

When you want to reach a camera recorder remotely without the camera maker's cloud service, set up a VPN into the office, run an in-house server, or a partner whitelists access by IP address. If you only view cameras through the maker's app, you usually don't need one yet.

Is a second line worth it?

If your business depends heavily on the connection, two lines from two different providers with a load-balancing router are often worth more than hunting for the single "best" provider. Small shops can use a 4G/5G SIM as a fallback for the POS.
