Mobile & SIM
Business mobile and data SIMs that work where you do
Mobile and data SIMs on the networks with the best coverage for your area, with pooled data and one simple bill — instead of juggling personal contracts across the team.
What it is
Plain-English, no jargon
Business mobile brings your team's phones and data SIMs onto contracts built for a company, not an individual — one invoice, pooled data across every user, and the ability to add or remove a line without a new 24-month contract each time. Because we're not tied to a single network, we place each SIM on whichever network actually has the best coverage for your part of Kent or the UK, rather than whatever one provider happens to sell. It also covers data-only SIMs for equipment — payment terminals, CCTV, vehicles and backup routers — billed and managed alongside your handsets on the same account.

No hard prices here on purpose — every quote depends on your address and current setup. Bands are a guide only.
Why not just use a single network provider?
Every mobile network has patchy spots — a signal that's excellent in Ramsgate might be weak in parts of the Weald, and vice versa. Locking your whole team onto one provider means everyone inherits that provider's blind spots. Because we're not restricted to one network, we can put each SIM on whichever network genuinely performs best for that person's usual locations, all managed under one account and one bill rather than several separate contracts.

Our support promise
No call centres. No scripts. Just people who know your setup.
Every fault gets a real response within minutes, not a ticket number. If something needs an engineer on site, we're usually there the same or next working day — because we're based in Kent, not a national call centre.
“Half our engineers were on a network with terrible coverage out toward the coast. Green Star moved just those SIMs to a different network under the same account — same bill, much better signal.”

FAQs
About this service
Can I keep my existing mobile numbers?
Yes, number porting is handled as part of onboarding at no extra cost.
Do you support data-only SIMs for equipment?
Yes — payment terminals, CCTV, vehicle trackers and backup routers can all sit on the same account as an IoT or data-only SIM.
What happens to unused pooled data?
It rolls into the shared pool for the rest of the team to use, rather than being wasted on a single line's individual allowance.
Can I mix contract lengths across the team?
Yes, individual lines can be added or renewed independently rather than being locked to one company-wide renewal date.
Is international roaming available?
Yes, roaming bundles can be added per line or per trip — let us know your travel patterns and we'll recommend the right option.
How quickly can new SIMs be issued?
Standard SIMs are usually issued within 2–3 working days; urgent replacements can be arranged faster.
