It appears that DiGi is one step closer in enabling 4G LTE for iPhones. If you’re an existing DiGi subscriber with an iPhone 5/5S, you should be getting a software update which enables LTE connectivity under Cellular settings.
However don’t get too excited just yet as DiGi’s 4G LTE service doesn’t seem to be working for smart phones right now. DiGi’s 4G LTE service is currently available for broadband & tablet use. In response, DiGi has tweeted that 4G LTE for smart phones would be coming soon but without mentioning when exactly.
When DiGi started its 4G LTE commercial service 6 months back, they were running only on LTE Band 7 (2600MHz). As comparison, the other LTE telcos such as Maxis & Celcom are running on both Band 3 (1800MHz) and 7 (2600MHz).
The latest iPhone 5S and iPhone 5C supports LTE on both 1800MHz and 2600MHz frequency while the previous iPhone 5 only supports 1800MHz. Ideally we hope DiGi would offer LTE on 1800MHz as well so that existing iPhone 5 users would get to enjoy 4G speeds too.
