smartphone for homeless man (st pancras N1C)

Hi. I am currently homeless and have lost my phone. I tend to use the library during the day and then sit in St Pancras station at night using their wifi. A phone is a massive lifeline to me as it not only means I can be in contact with my outreach team but I also have some form of entertainment as well. I fanyone please has an old basic smartphone or tablet that would allow me to access emails and also watch Youtube I would be eternally grateful. I can check message responses each day in the library and meet anywhere local. Thanks in advance.
