New Zealand cellular operator 2degrees has announced that it will close down its 2G GSM/GPRS/EDGE network in March 2018. The firm says all phones it has sold since 2015 have been 3G or 4G capable, and the 2G system now accounts for a ‘small and declining’ percentage of users. 2degrees says it will be contacting those customers with 2G-only handsets to remind them that they have six months to upgrade to a 3G or 4G model. The cellco’s W-CDMA 3G network now provides coverage of 98.5% of New Zealand’s population. The 900MHz and 1800MHz frequencies freed up by the 2G switch-off will be migrated to 4G services.
