Jola has added a range of multi-network roaming data SIM packages to Mobile Manager, its online management portal for ordering and managing estates of mobile data SIMs.
The white label portal communicates in real-time with multiple 4G networks and can be used by both resellers and their end users.
Mobile Manager handles SIM activations, ceases, suspensions, reports, alerts and bolt-ons.
Cherie Howlett, Marketing Director, said: "We are seeing increased demand for data SIMs that always choose the strongest signal and work across Europe on the same tariff.
"Jola's multi-network European roaming SIMs each have three major networks and 42 countries.
"Even if two mobile towers are out of commission the SIM will continue to work and by using Mobile Manager, resellers can monitor usage and add bolt-ons to maximise margin and eliminate the danger of bill shock for their customers."
