If you’re thinking about getting an AlterLock Gen3 for a bike you ride well beyond city streets \u2014 into the hills, along canal towpaths, or out to more remote trailheads \u2014 there’s a fair question worth asking before you buy: will the GPS tracking actually work out there? The honest answer is: it depends on where “there” is, and this article is about giving you the tools to check that for yourself rather than assuming it’ll just work everywhere.<\/p>\n\n\n\n

How AlterLock Gen3 Stays Connected<\/h2>\n\n\n\n

Gen3 uses two different connections depending on distance. When your phone is nearby, it talks to the app over Bluetooth. When you’re further away \u2014 which is exactly when tracking matters most \u2014 it switches to LTE-M or NB-IoT, low-power cellular standards built for long-range, battery-friendly communication (AlterLock: How Gen3 Works<\/a>). The device also sends a routine location update every 6 to 24 hours regardless of lock status, so even a bike sitting untouched has a recent position on record.<\/p>\n\n\n\n

The part that matters for this article: LTE-M and NB-IoT aren’t magic. They’re radio signals, and like any cellular signal, they only reach as far as the network operator’s towers do.<\/p>\n\n\n\n

Where Coverage Is Strongest<\/h2>\n\n\n\n

LTE-M antennas are added to existing mobile phone towers \u2014 the same infrastructure your own phone connects to. That means coverage tracks very closely with where people, and therefore towers, already are: towns, cities, and other densely populated areas. If you’re commuting, running errands, or riding within a built-up area, you’re riding through exactly the parts of the network operators have invested in most heavily.<\/p>\n\n\n\n

Where Coverage Can Be Weaker<\/h2>\n\n\n\n

The flip side is just as important to say plainly. In sparsely populated countryside, forests, and over open water such as lakes, signal can be patchy or absent. This isn’t unique to AlterLock \u2014 it’s a property of cellular networks generally. Ofcom’s most recent Connected Nations report found that 96% of the UK landmass has 4G coverage from at least one network operator, but only 81% has it from every operator, and the gaps concentrate in the most rural parts of the country \u2014 Scotland, Wales, and the North East are consistently reported as having the lowest 4G landmass coverage in the UK (Ofcom Connected Nations 2025<\/a>). Even at the premises level, where coverage is generally much better than across raw landmass, Ofcom’s England-specific report found that 99% of rural premises have voice coverage from at least one operator \u2014 meaning the remaining 1% still has none at all, and that’s before accounting for the harder problem of open countryside between properties (Ofcom Connected Nations 2025 \u2014 England<\/a>).<\/p>\n\n\n\n

There’s a simple reason these gaps line up with the places people find hardest to reach on foot or by bike in the first place: network operators build towers where there’s enough population and traffic to justify the cost. A remote hillside, a dense stretch of forest, or the middle of a lake are exactly the kind of places that are expensive to cover and light on everyday users \u2014 which is also, unhelpfully, where you might most want tracking to work if something goes wrong.<\/p>\n\n\n\n

How to Check Coverage in Your Own Area<\/h2>\n\n\n\n

Rather than guess, you can look this up directly. Vodafone publishes a Network Coverage Checker<\/a> that lets you enter a location and see signal strength specifically for NB-IoT and LTE-M \u2014 the same category of network AlterLock Gen3 uses, not just ordinary phone signal. It reports results in RSRP bands ranging from “Good” down to “No coverage,” with a couple of intermediate levels in between, so you can get a real read on your regular routes, your storage location, and anywhere else you’d want the device to keep working.<\/p>\n\n\n\n

A few sensible places to check before you buy or before a specific ride:<\/p>\n\n\n\n
