I was abroad helping my ex-wife to provide palliative care to her sister who had stage 4 cancer. When I came home I found I had forgotten my phone and I'm 73 with a poor working memory. I have called my ex-in-laws but they haven't found it.

I just need a an Samsung or Google phone because now when I try to buy things I ned online - Christmas coming is not helping - I fail to get a code from 2-Step authentication because I no longer have a mobile phone. No App no authentication! Please can someone help me? I live in Greenwich.

samsung or google phone (Greenwich SE10)
