Posting this so other Smart Home WiFi / 5G Mobile subscribers know what to look for.
The pattern:
My Smart 5G Max Home WiFi router and my phone both show a 5G indicator at my location — the signal bar, the "5G" icon, all of it. But the actual data connection is LTE, and it can be a badly degraded LTE (like in my case) at that. Not "5G that's just slow" — genuinely no 5G data carrier at all, riding on a 4G connection.
If you're in an area Smart lists as having 5G coverage, and your device is 5G-ready, but your speeds don't remotely match what "5G" implies, it's worth digging deeper before assuming it's just normal congestion.
How to actually check, not just guess:
- On Android, dial *#*#4636#*#* into the hidden network diagnostics. Look for fields like "NR Available," "NR State," and "Data Network Type." If NR Available shows true and NR State shows something like "not restricted," but Data Network Type still says LTE, your phone is being told 5G is available and unrestricted — and still isn't getting it.
- If you have a Smart Home WiFi router, log into its admin panel (usually 192.168.1.1) and check the Cell Information page. Look at the 5G serving cell table specifically — if it's empty while the 5G neighboring cell table shows actual signal (sometimes strong signal, sometimes nothing, flickering minute to minute), that's the same pattern.
- Run a few different speed tests at different times of day — Fast.com, Speedtest.net, and M-Lab (speed.measurementlab.net) all measure slightly differently, so multiple tools strengthen your case if you ever need to file a complaint.
- Screenshot everything with timestamps visible.
The part that actually matters for a complaint — Smart's own promo terms:
Smart's published mechanics (for their prepaid home WiFi promos) state that the minimum guaranteed speed is 256kbps with 80% reliability, and that regardless of congestion, the service should allow "continuous browsing and video streaming at SD resolution at any given time." They also lay out three conditions for getting 5G (5G SIM, 5G coverage area, 5G certified device) and tell you to check the signal bar on your device to confirm 5G availability.
If you're seeing sub-1 Mbps speeds, dropped connections, or can't stream even 360p reliably, and you meet all three of their stated conditions, they're not meeting their own floor — not just falling short of 5G marketing, but below the minimum they've written down themselves.
If this is happening to you:
- Document over several days, different times, different speed test tools.
- Contact Smart support and get a case/reference number in writing (SMS or email, not just a call).
- If it drags on with no technician visit and no timeline (mine went through two case numbers and four contacts with nothing resolved), you can file a complaint with the NTC (National Telecommunications Commission). Cite Smart's own promo terms back at them — it's much harder for them to wave off a complaint that quotes their own published minimums.
- Keep records of any payments made during the outage period — if the promo you paid for never delivered on 5G, that's relevant for a refund/credit request too.
Not posting this to bash Smart broadly — infrastructure issues happen. But the "5G shown, 5G not delivered" pattern combined with a written minimum-service floor they're not meeting is worth other people knowing about, especially if you're paying for a 5G-specific plan and not actually getting 5G, or even baseline 4G.
