Lycamobile, a multinational MVNO hailing from London, is raising serious accusations against T-Mobile, their US network partner since 2012. They cite considerable hurdles in acquiring basic services like eSIM and access to T-Mobile’s 5G standalone architecture. Lycamobile’s stance escalates further; by urging regulatory bodies to halt T-Mobile’s looming acquisitions, they imply an uneven playing field. Meanwhile, T-Mobile, combating allegations of litigation as a diversion, asks that Lycamobile’s claims be dismissed.
