Card Machine That Runs on 4G Only With No WiFi

Yes, several UK card machines run on 4G only with no WiFi required. SumUp Solo (£99), Dojo Go (£40 monthly), Zettle Terminal (£149), Square Terminal (£149) and most Worldpay Move terminals all carry built-in SIM cards. Multi-network SIMs roam between EE, Vodafone, O2 and Three. No broadband or WiFi setup is needed. Useful for mobile traders, market stalls, callouts, and any location where WiFi is unavailable or unreliable.

What this means for your business

4G-only card machines remove the WiFi dependency. Each device carries its own SIM card with a data plan included in the device cost (facilitators) or in the monthly fee (traditional acquirers). The terminal connects directly to the mobile network and processes transactions without any further network setup. This is the only realistic option for mobile traders, market stalls, and outdoor venues without reliable WiFi.

Multi-network SIMs are now standard on most UK 4G card machines. The device picks whichever of EE, Vodafone, O2 or Three has the strongest signal at the moment, and switches seamlessly between networks as you move. This dramatically improves reliability in rural areas and inside large venues where one network might be patchy while another is strong. Older single-network devices (some legacy Ingenico and Verifone models) struggle where the chosen network has dead spots.

Data plan caps vary. Facilitator devices (SumUp Solo, Zettle Terminal, Square Terminal) include the data in the device cost with no separate monthly fee for the SIM. Traditional acquirer devices (Dojo Go, Worldpay Move) include the data in the monthly device fee. Caps are usually far above what a single device would use (multiple GB per month) and most merchants never approach the limit. If the device runs more than 1000 transactions per day, check the cap with the provider.

Key points

4G-only card machines remove the WiFi dependency, useful for mobile and outdoor traders
Multi-network SIMs roam between EE, Vodafone, O2 and Three
SumUp Solo, Dojo Go, Zettle Terminal, Square Terminal and Worldpay Move all support this
Data plan is included in the device cost or monthly fee, no separate SIM contract
Data caps are usually multiple GB per month, well above typical merchant use
Direct mobile network connection means no WiFi setup, no router configuration
4G drops to 3G or 2G in congested events but transactions still complete, just slower

Common pitfalls

Choosing a single-network SIM device for cost, then losing transactions when that network has a bad day
Forgetting that 4G signal is suppressed inside large metal-framed buildings (warehouses, marquees), test before opening
Assuming the data plan is unlimited, very high-volume merchants can hit a cap
Tethering through your phone when the device SIM should work, this masks a SIM issue that needs resolving
