Everyday tech, from zero

Your phone is your camera, your bank, your work inbox and your photo album. A few minutes of setup protects all of it.

• Updates on. Updates close security holes that criminals use. Turn on automatic updates and install them when your phone asks.
• A real screen lock. A 6-digit PIN or more, plus fingerprint or face unlock. Avoid 123456, birthdays and simple patterns.
• Backup on. Android: Google One backup. iPhone: iCloud Backup. If the phone is lost or stolen, you get your photos, contacts and chats back on the new one.
• Find my phone on. Android has Find My Device, iPhone has Find My. They let you locate, lock or wipe a lost phone.
• Free up space. A full phone gets slow. Clear old WhatsApp videos and voice notes first — they are usually the biggest culprit.

Most Wi-Fi trouble isn't the internet plan — it's where the router is and how it's set up.

• Move the router. Central, high up, out in the open. Not on the floor, not inside a cabinet, not behind the TV. Concrete walls and metal block the signal.
• Restart it once in a while. Unplug for 30 seconds. It clears a lot of slowdowns.
• Know your two bands. Many routers have 2.4 GHz (goes further, slower) and 5 GHz (faster, shorter range). Use 5 GHz near the router, 2.4 GHz further away.
• Change the default password. And the router's admin password too. Anybody who visited and saw the sticker can get in otherwise.
• Still have dead spots? Then consider a mesh system — two or three small units that share one Wi-Fi name around the house. It usually works better than a cheap extender.

Lightning, power cuts and the surge when current comes back can kill electronics in one shot. Protection is cheap compared to replacing a TV or fridge.

• Surge protector — not just a plain power strip. Look for a joule rating on the box (higher is better). Replace it after a big strike; they wear out.
• Small UPS (a battery box) for the router and modem keeps your internet up through short outages, and lets a desktop computer shut down safely.
• Voltage protector for the fridge, freezer and AC. It waits a few minutes after power returns before switching them on, which protects the compressor.
• Thunderstorm overhead? Unplug what you can, including the TV's cable or antenna line.
• Bigger backup (an inverter with batteries, or solar with batteries) can keep lights and fans going for hours. That's a bigger spend — get a qualified electrician to quote and install.

A smart plug lets you switch something on or off from your phone, or on a schedule. It's the easiest way to start a “smart home”.

• Good uses: lamps on a schedule so the house looks lived-in, a fan that turns off after you fall asleep, a coffee maker or decorative lights.
• Check the rating. Every plug has a maximum load (in amps or watts). Don't use a small plug on an AC, water heater or anything that heats — unless it's rated for it.
• Energy monitoring plugs show how much electricity a device uses. Great for finding the old fridge that's eating your bill.
• Stick to one app. Pick a brand that works with Google Home or Apple Home so you're not juggling five apps.
• Wi-Fi matters. Most smart devices only use 2.4 GHz Wi-Fi, so set up near the router if it struggles.

Cameras have become cheap and easy. Before you buy, think about where the video goes and who can see it.

• Cloud or local? Cloud storage usually needs a monthly fee. Local storage (a memory card or a small recorder) has no fee but can be stolen with the camera — some systems do both.
• Change the default password and turn on 2-step verification on the camera app. Weak camera accounts are a common way strangers get access.
• Update it. Buy from brands that still send updates. Cheap no-name cameras often never do.
• Point it right. Cover your gate, car and doors — not your neighbour's yard or windows.
• Power and Wi-Fi. Check the signal where the camera will go. A camera that keeps dropping off is useless when you need it.

Air conditioning, fridges and water heating usually use the most power in a home. That's where to look first.

• Inverter AC. Inverter models adjust their speed instead of switching fully on and off, so they usually use noticeably less power. Worth it when replacing an old unit.
• Set the AC around 24–25°C and close doors and curtains. Every degree cooler costs more.
• LED bulbs use a fraction of the power of old bulbs and last for years.
• Fridge check. If the door seal doesn't grip a sheet of paper firmly, cold air is leaking out.
• Solar. Solar water heaters and rooftop panels are getting cheaper. Electricity here is cheaper than on many islands, so the payback can take longer — get two quotes and ask how many years it takes to pay for itself.

Google Docs and Microsoft 365 let several people work on the same document, sheet or slideshow at the same time — from a laptop or a phone.

• One file, one link. Instead of “final_v3_REAL.docx”, everybody opens the same file.
• Share carefully. Choose Viewer, Commenter or Editor for each person. Avoid “anyone with the link can edit” for anything important.
• Version history lets you go back to an earlier version if somebody deletes something by mistake.
• Works offline too if you turn it on, and syncs when you're back online.
• Free to start. A free Google or Microsoft account comes with some storage; paid plans add more space and business features.

Most work calls now happen on Zoom, Teams, Google Meet or WhatsApp. A few habits make a big difference.

• Light in front of you, not behind. Face a window, don't sit with your back to it.
• Earphones stop echo and background noise. Mute when you're not talking.
• Test first. Join five minutes early to check your mic and camera.
• WhatsApp Business (free) lets a small business set an away message, quick replies, a product catalogue and business hours — and keeps work separate from personal chats.
• Weak data? Turn off your video and keep the audio. It's better than freezing.

More and more of everyday business can be done from your phone, without standing in a line.

• Online banking. Use your bank's official app, from the official app store. Turn on transaction alerts so you see every charge.
• Online shopping card. Many people use a separate card with a low limit just for online purchases. If it's ever stolen, the damage is small.
• Government services. The ttconnect portal is the official starting point for many government services and forms.
• Scan with your phone. Google Drive (Android) and Notes or Files (iPhone) can scan documents into clean PDFs. Keep copies of your ID, certificates and receipts in a private, backed-up folder.
• Go paperless gradually. Start with bills and receipts — they're the easiest to switch.

Most accounts get broken into because of reused or weak passwords. Fixing that stops most trouble.

• Long beats clever. Three or four random words together (like mango-ferry-pothole-sunset) is stronger and easier to remember than P@ss123.
• Never reuse your email or banking password anywhere else.
• Password manager. The one built into your phone or browser (Google Password Manager, Apple Passwords) remembers them for you. You only remember one.
• 2-step verification asks for a code or approval on your phone when someone logs in. Turn it on for email first, then banking, social media and WhatsApp.
• Check for leaks. Have I Been Pwned tells you if your email showed up in a data breach.

Scammers use the same few tricks over and over. Once you know them, they're easy to spot.

• “I sent you a code by mistake.” Never send anybody a code you received — not even a friend. That code is the key to your WhatsApp or bank.
• Fake delivery messages. A text saying your package is held and you need to pay a small fee. Check directly in your courier's official app or website instead.
• Bank “security” calls or texts. Your bank will not ask for your PIN or full password. Hang up and call the number on the back of your card.
• Urgent family emergencies. A voice note or call asking for money fast. Voices can be faked now — call the person back on their usual number.
• Too-good jobs and investments. Pay to get a job? Guaranteed returns? It's a scam.

The rule: if it's urgent, emotional and asks for money or a code — stop, and check another way.

The best tech purchase is one that solves a real problem and lasts.

• Start with the problem. “My laptop takes 5 minutes to start” is a problem. “There's a new model out” isn't.
• Check more than one review and ignore the star rating alone — read what people complain about.
• Warranty at home. Things shipped in through a courier may not have a local warranty or repair support. Factor that in.
• Power and plugs. T&T uses the same type of plugs and voltage as the US (around 115V). UK and European items often need a different plug and voltage — check before buying abroad.
• Total cost. Add shipping, duties and any monthly subscription to the price tag.
• Refurbished from a reputable seller can save a lot on phones and laptops. And dispose of old electronics properly — they contain batteries and metals that shouldn't go in the regular garbage.
