Sales manager Simon Gardner said: "Is a lack of mobile phone signal costing your business time and money? Don't let it impact your customer's experience or service.
"There is nothing more frustrating than trying to organise workers and run a business with little or no phone signal. Your business needs to stay connected, no matter where you and your staff are.
"Every year we see mobile networks claim they have the best network coverage, but blackspots remain a problem across the UK and no one provider is perfect.
"This is where Lister comes in. Our multi-network voice SIM cards give business owners and workers access to O2, Vodafone, EE and Three network coverage for voice text and data, all on one sim card - dramatically improving connectivity wherever you are."
"For a long time, we have been supplying multi-network data sims to businesses, so that machines can talk to each other without the risk of outages, and now your people can too."
Whether it's for a security guard, farmer, mobile engineer, builder, HGV driver or factory worker, Lister claim that these advanced voice SIMs allow for communication without the worry of ‘dead-zones’ - perfect for working-on-the-go in remote locations.
If you are already using a Dual SIM mobile device, the business also said that using a multi-network voice SIM as aback-up will give you greater flexibility and a much wider range of choices for using data, voice, and text services.
