I was trying to get my phone plan to work while I am abroad for 3 months. I first tried to upgrade my vodafone plan through the website, but this of course does not work on their awful site so you have to talk to the awful chatbot and when it inevitably doesn't work you have to wait 100 places in a queue to talk to someone. After I got an adviser, they offered me the ridiculous prices of £32 a month or £25 a month with an additional £2 daily charge everyday I would use it. These extortionate packages offered only 100 minutes abroad, so I obviously didn't take these. I then tried to apply for a voxi sim card because they seemed reasonable, but I wouldn't be able to keep my number if I got a new voxi card because I already had a vodafone plan so for some reason the PAC code wouldn't work to transfer the number (ridiculous that this is a rule). I was then told I could get a voxi plan on my santander card instead, and was transfered between 3 people before being told I had to be in the UK to have the voxi plan on my card. They then suggested I send my current card back to the UK to then have the voxi plan put on it and then have it sent back to me in spain. This all took around 4 hours of sitting on the chat system on both voxi and santander sites. At every step throughout this horrendous ordeal I was asked to supply a security code. I had to repeat EVERY SINGLE TIME that I was abroad and could not receive any messages or calls to receive the code. I was transferred even more between different people because of this code issue. If I could have paid for the code message to go through to me if I could have, but vodafone's applications and integration to android phones is so bad that this option is nowhere to be found. Do not use vodafone, get an infinitely better deal from literally anywhere else.
