Agree. Totally my experience with 4GX and Telstra. At home I need to put the Telstra device in one of two windows to hit 2 bars and a reliable service at speeds not much better than 3G. Away it can be very good. Video streaming and email. Buildings, forest etc still seem to impact 4G in some locations, hence the option for an antenna is important.
I’d suggest Telstra 4GX is in the same ball park performance as Optus 4G LTE (Plus), although that I access with an iPhone 8 which has no external antenna option.
For anyone lucky enough to live close to a Telstra 5G micro cell better news perhaps.
But $129 for the 160GB you noted it looks not so sweet. That’s also less than 5hrs of data at 100Mbps data rate. Which is much less than 5G is capable of. It is one big premium to save milliseconds on down loading the email?
More cute than sweet on Telstra’s behalf given Optus will do 100GB for $60pm on sim only, or 200GB for $65pm on fixed mobile data on a contract and throw in the 4G Plus modem.
There is also an Optus plan for 500GB, only $85pm.
Yes you need to live in an area with reliable Optus coverage and accept likely limitations at peak times. For a casual user a little data can go a long way!
