MTN Shesh@ 600 issue - Missing "300GB at best 5G speeds" Data Since Jan 2026

I’m extremely frustrated with my MTN Shesh@ 600 5G home internet package.

The deal is supposed to give 600GB per month: "300GB at best 5G speeds", then "300GB at 30Mbps", and only after both have been exhausted should it be throttled to 512kbps.

Since January 2026, I have NOT been receiving the first "300GB at best 5G speeds" allocation at all. Every month from the 1st, my line immediately starts on the 300GB @30Mbps tier, and once that finishes I get throttled to unusable speeds of 512kbps.

I only received the "300GB at best 5G speeds" allocation for the first 3 months (Oct–Dec 2025). Since then, it has been missing every single month.

I have been raising this issue since February 2026 and have received no joy or assistance. I’ve contacted MTN multiple times, logged multiple incidents, spoken to their coverage team, reset my line and reset my router. From my experiences it seems the MTN support staff don't understand the products MTN sells. I’ve been told everything is provisioned correctly or that it’s a coverage issue, but nothing ever changes. I am also in a confirmed 5G coverage area and have received the full allocation before, so this is clearly not a coverage issue.

This effectively means I’m paying for a 600GB 5G package but only receiving half of it as advertised. I’ve provided invoices and usage proof showing the same pattern every month.

If this issue cannot be properly investigated and resolved with a clear explanation, then it is clear the service is not being delivered as advertised and I will escalate this further through the appropriate regulatory and consumer protection channels.

I trust MTN will resolve this issue timeously.
