GOMO SIM is a SIM card offered by GOMO, a fully digital telco that operates as a mobile virtual network operator (MVNO) . This means that GOMO does not own any radiofrequency and instead enters into a business agreement with an MNO, such as Globe in the Philippines, to use its network for its services. Having a GOMO SIM card does not give any technical advantage in terms of signal reception and download speeds. The GOMO SIM card is assigned a unique personal identification number (PIN) and personal unlocking key (PUK) codes that are printed on the SIM bed, which the user should keep safe and secure at all times. Claims of defects in the GOMO SIM card shall be entertained if brought to GOMOs attention within seven (7) days from the date of purchase and only if there has been no prior usage and if it has missing, incomplete, or unclear card numbers (including PIN or PUK codes) . The GOMO SIM card is used with a SIM-based mobile device specific to the SIM Pack and is not SIM-locked to networks other than Globe.
