I imagine it has to do with the 4G roll out. The fact that they're rolling out 4G at the end of 2019 says it all. 48 are keeping relatively quiet about all this, but they have said that people experiencing network loss since the roll out should order a sim. I imagine there's a large volume of customers ordering new sims and trying to activate them, which may be contributing to the issue.
48 should consider that the majority of their customers pay for a monthly membership and now those customers are blocked from using the membership they paid for because this roll out has forced people to lose service. The only reason I haven't swapped to a new network provider yet is because I still have significant credit on my account, although at this stage I'm considering cutting my losses, one week with no phone service is ridiculous.
