LycaMobile does not offer services with a monthly bill the way most cellular service providers do. Instead, a monthly plan is purchased for a one time flat fee paid at the time of purchase. Any overages can be handled by a SIM card rechargeable on the company's website.
Despite the flat fee nature of the monthly plans, extras such as roaming charges and additional minutes beyond those included in the chosen plan can increase the total cost. Additional minutes can be purchased for one cent each, while they cost five cents if no plan has been purchased. The most cost effective option is therefore to choose or renew a plan each month.
