1. Can one username log in on several devices at the same time?
Home customers expect one plan to cover the phone, the laptop and the TV. Many setups allow one device per username, and the second device gets "no more sessions allowed". Ask how the limit is set per plan, and whether it still holds when something goes wrong, like a power cut. Our guide to multi-device home plans covers how to price and sell them.
In T-Net: each plan has a device limit from 1 to 5, and every device on the account can be online at the same time.
2. Do devices sign back in on their own?
If customers have to type a password every time the Wi-Fi drops, they will call you, or share one password with the whole street. Ask how a device is recognized when it comes back, and test it with a recent phone, since many phones now change how they identify themselves to each Wi-Fi network.
In T-Net: each device is remembered for 30 days and reconnects without a password, recent phones included.
3. Can you reach routers that have no public IP?
Most small networks sit behind mobile data or a shared connection, so the router has no address you can reach from outside. A platform that needs to connect in to each router won't work there. Ask whether the router connects out to the platform instead.
In T-Net: each MikroTik opens an encrypted WireGuard tunnel to T-Net, so you can manage it from anywhere with no public IP.
4. What happens when a router loses power?
A router that loses power never reports that its users went offline. Unless the platform notices, those sessions stay open, count against device limits and keep customers locked out. Ask how stale sessions are closed, and how quickly you hear that a router is down.
In T-Net: stale sessions are closed automatically, and you get a Telegram message when a router goes offline and when it comes back.
5. What happens when a customer runs out of data?
Cutting the connection off completely means an angry call. Slowing it down usually means a renewal. Ask whether you can choose, per plan, and whether the change applies straight away without the customer reconnecting.
In T-Net: plans can be sold by data, by time or both. When the data runs out, the connection drops to a slower speed you set on the plan.
6. How are vouchers and sale points handled?
If you sell through shops and agents, the voucher system is where money goes missing. Ask how batches are printed, how each sale point's commission is worked out, and whether the platform notices vouchers sold in one area and used in another.
In T-Net: vouchers are generated in batches with QR codes and printed on your own templates. Sale points can work on commission or buy vouchers upfront, and T-Net flags a sale point whose vouchers mostly get used on another branch's network.
7. Do the money figures match real usage?
A report that says you sold 400 vouchers is only useful if 400 vouchers were really used. Ask whether payments can be edited after the fact, and whether anything checks them against the RADIUS records.
In T-Net: payments can't be edited or deleted, only reversed. Every day T-Net checks payments against usage, and each month's settlement is cross-checked against the RADIUS records.
8. Is each branch kept separate?
Once you run more than one town, or work with partners, each branch's staff should only see their own customers and money. Ask how that separation works, and whether staff in one branch can sign in to another.
In T-Net: each branch has its own address, staff accounts, login page and reports, and staff sign in at their own branch's address only.
9. Who do you call when something breaks?
Support that answers in another time zone, days later, is not much use when a base station is down on a Saturday. Ask where the support team is and how you reach them.
In T-Net: support is in Paynesville, by phone or WhatsApp on +231 55 535 3438, Monday to Friday 8 AM to 6 PM and Saturday 9 AM to 2 PM.
Test before you move customers
If a vendor can't answer one of these clearly, try it on a spare router before you move real customers. Log in with two phones on one plan, pull the router's power cable, and see what the dashboard says afterwards. It takes an afternoon and tells you more than any feature list.
