I'm starting a job on the border of rural northen victoria soon and will be driving around a lot through iffy reception areas, even just to get to the office from home. I believe work supplies a phone, laptop and GPS tracking/alarm on full telstra for safety reasons (registered nurse / psychiatric role FTW) but I want my personal phone ergo provider in my own car to be upto snuff in case I use it and a fleet car isn't available, left work phone at work, wife calls, etc. I've been using Aldi for a while, they are not and will never be all that reliable, they don't have full rural networks as a telstra MNVO, so full telstra it is. I don't see Boost being much better than aldi except it has the full telstra network and my gut reckons it's budget for a reason. The main question however, is if there any difference at all how the telstra towers interact with a prepaid vs plan sim/phone. Prioritisation, reception, reliability in general - anything. I'd just get a telstra plan and be done with it but I am a cheapskate at heart I'd rather pay $300 per year for a yearly prepaid than $600 for a plan, that simple. That said, if the plan is better for reliability than prepaid in some tangible way, that is something I will pay the difference for. Just in case anyone is curious, I use a oneplus 7 and more importantly I've got a strike cradle and antenna for the car. Strike are a known quantity and pretty damn good quality. I'm not sure if my fleet car will have this sort of setup.. if it doesn't, it will while I'm in it.
