Company phones or personal phones
There are two common approaches. Company-owned phones are bought or leased by the business, use business numbers and are returned when staff leave. Bring your own device (BYOD) means staff use their personal phones for work, sometimes with an allowance. Both can work, but they need different policies and different security setups.
Company-owned phones give the business full control: it can enforce security settings, wipe the device if it is lost and keep the number when someone leaves. BYOD is cheaper upfront and staff only carry one phone, but the business can only manage the work side of the device, and customers may end up with a staff member's personal number. Decide which approach you want, write it down and apply it consistently.
Choosing a business plan
Business mobile plans often allow pooled or shared data across all connections, which suits teams where some people use a lot and others very little. Look at your actual usage over a few months before picking a tier. Check what is included: calls to Australia or other countries you deal with, roaming, and whether hotspot use is allowed.
Ask about account management. A good business account lets an administrator add and remove lines, set spending limits, block premium services and get one consolidated bill. Make sure the account is in the business's name with more than one authorised contact, so you are not locked out if the person who set it up leaves.
Compare total cost over the full contract rather than the monthly figure alone. Handsets bundled into a plan can look cheap per month while adding hundreds of dollars over two or three years, and leaving early may mean paying out the remaining handset balance. Buying phones outright and taking a shorter, SIM-only business plan often works out cheaper and gives you freedom to change provider when a better deal appears. Whichever you choose, put the renewal date in a calendar so the contract does not roll over unnoticed onto a worse rate.
Owning the numbers
A mobile number given to customers becomes part of the business. If it sits on a staff member's personal account, it leaves with them. Keep customer-facing mobile numbers on the business account, and if staff use personal phones, give them the cloud phone system's mobile app so they call from the business number instead. When onboarding someone with a company phone, record the number, handset model and serial, IMEI and the date issued. When they leave, collect the phone, reset it and either reassign the number or set up a voicemail message directing callers to the right person.
Securing phones with device management
Phones hold email, files, Teams chats and often the authenticator app that protects staff accounts. A lost unlocked phone can expose a lot. Mobile device management (MDM), such as Microsoft Intune for Microsoft 365 businesses, lets you require a passcode, keep the operating system updated, encrypt the device and wipe work data remotely.
For company-owned phones, full management is appropriate. For personal phones, app protection policies can protect just the work apps, so the business can remove work email and files without touching personal photos and messages. Explain this clearly to staff so they understand what the business can and cannot see on their personal device.
Policies that prevent problems
A short mobile phone policy covers who gets a phone, acceptable use, what happens if it is lost or damaged, whether personal use is allowed, and the requirement to report loss immediately. It should also cover overseas travel, including roaming charges and any security precautions for countries you visit. Keep a register of every business mobile: who has it, the number, the model, its purchase date and whether it is enrolled in device management. Phones older than the manufacturer's update window stop receiving security patches, so the register also tells you when to replace each one.
Remind staff never to approve sign-in prompts they did not start, to keep their phone updated and to avoid installing unknown apps on any device holding work data. These habits protect your accounts as much as any setting does. Review the policy once a year or when you change mobile provider.
Poor coverage inside the office
Some buildings block mobile signal, which frustrates staff who rely on their mobiles. Wi-Fi calling, supported by most current phones and many plans, routes calls over the office Wi-Fi when signal is weak. Turn it on and confirm with your provider that your plan supports it. If Wi-Fi calling is not enough, the cloud phone system's mobile app also works over Wi-Fi. In larger buildings, approved mobile coverage solutions exist but must be arranged with the network operator; unapproved signal boosters can interfere with networks and are not legal to use in New Zealand without approval.
In short
- Decide between company-owned phones and BYOD, and write it down.
- Keep customer-facing numbers on the business's account.
- Use device management to protect work data on every phone.
- Have a clear process for lost phones and staff leaving.
- Turn on Wi-Fi calling where indoor signal is weak.
