While Lycamobile represents the core business of Lyca, namely the offering of a MVNO telecommunications services, Lyca has other telecommunication services provided to consumers:  GT Mobile (also known as "Gnanam Telecom") is a MNVO sub-brand of Lycamobile that operates in Denmark, Germany, The Netherlands, Sweden, Australia, Spain, Italy, France, Belgium and Switzerland (the United Kingdom arm has been merged in Lycamobile). The brand, like its parent, is aimed at those who wish to make national and international phone calls on a pay-as-you-go basis. The GT Mobile brand offers alternative pricing structures and packages focusing more on national bundles from the Lycamobile brand. Lycatel is focused on the sale of calling cards to wholesalers to then sell on to the public. Lycatel offers online sales of calling cards and direct customer sales through the Lycateleshop. The Lycatel brand is not itself used as a calling card brand name, but acts as a parent brand name used on various branded calling cards. The most popular brands of Lycatel calling cards include Africa Tel, Cobra, Eurocity, One+One, Spicy Tel, Supertel, Unitel, Viper and World Call. Each calling card brand features different calling rates to different destinations with some being more suited to single use (known in the calling card industry as 'throw-away cards'). Others are more suited to occasional use but will feature a higher standard rate for each call placed. Whilst there is a fair level of confusion between pricing, Lycatel's underlying charges are significantly less than connecting international calls in a conventional sense. The Lycatel (or as previously used "Lyca Tel") brand has been in existence since 2001 although its early ownership and operational structure were significantly distinct in the early 2000s from the present day. The present-day Lycatel brand owners and licensees form a larger organisation although the operational focus of Lycatel remains the sale of a variety of differently branded calling cards to wholesalers. Wholesalers in turn sell onto retailers who then sell primarily to expatriate customers who want to make low-cost international calls. Lycatel primarily operates via its own national reselling companies or through its service providers in Australia, Austria, Belgium, Canada, Denmark, France, India (an outsourcing operation), Ireland, Italy, Netherlands, Norway, Portugal, Romania, Spain, Sweden, Switzerland, United Kingdom, United States and Tunisia.
