I used my mobile as a hot spot while on holiday in Mallorca in April. I use Euro Pass and had been browsing on the phone with data usage as expected. As soon as I switched on the hot spot the remaining data drained within seconds. I bought additional data and the same happened. I then changed the hotspot access password on my phone and bought additional data. Again it drained in seconds before I was able to connect my laptop. Is there any explanation for this? The phone works fine as a hotspot in the UK with the same laptop.
