Yes. I've had a few one day wobblers in the last while, one I seemed to have solved by pulling the sim, and trying it in a different phone, then putting it back in my own. This made the system push the AP settings again, and reasonable data resumed. I had another bad one right in the middle of Naas, plenty of reception but rubbish speeds, 0.1M, so I emailed support and the guy replied, asked to restart phone etc, said he'd log it with Vodafone. It came back good the next morning, but it's hit and miss, reception just OK where I live, data can be great one day, 1-2Mb the next. I think it's prioritising big money VF plans, so you only get good speeds if the premium customers are in a lull. My local speed at home right now is poor. Just over 1. Here's a mix of tests since the 0.1 one in April, some in city/towns, some at home in the sticks. The first 3 on the 26/5th after the 0.98 wifi connection were in Liffey Valley Lucan NCT centre. Even though it showed poor but usable speed, there was no Internet connection at all, which was a different problem entirely

I had trouble getting a page to load smack in the city centre Wednesday morning about 11.00. Same old story I thought as I popped on Speedtest to get some evidence for another snarky email. Sure enough, 1mb speed, but that wasn't the full story, the delivery all occurred in a burst towards the end of the test window. I repeated it, same result. Opened a web page, it just sat there trying to load. Then I returned to Speedtest, while the page load struggled, and the last two tests occurred.
I've never seen 80Mps before, but what's going on? And the upload is still rubbish. It took over 3 minutes to wake the 4g data pipe. What was it doing in the meantime?
It's nearly 50 years since I commenced my studies of circuit theory in the famed Kevin St, now demolished, but I recall that there was a definition of a connection as either circuit switched or packet switched, and somewhere in there is a subclass of constant connection v on demand. I think that AnPost data connections are almost fully disconnected during idle, so when you use it there is a huge delay setting up the path, not to your desired web or Internet server, but setting up the actual data delivery layer from your phone out of the Vodafone layer to whatever data comms company fulfills AnPost connections and internet traffic forwarding, (the 'Data Link' layer on the 7 layer model for any IT/comms engineers reading this).
The latency on the first three of those tests was nearly 1.6 to 2.6 seconds, dropping to 0.8 on the last. Thats like I was connecting via a switch on the moon and back. The Vodafone link speed is there, but it takes so long to negotiate a connection with the second rate service provider anpost are using that most of the time no data of significance is transferred. A packet here, a packet there. By all means vote with your feet if it stays like this.
