As a UK resident, for several years I have often used the excellent T-Mobile (app) 'unlimited' e-Sim for trips to the US lasting between 30 and 60 days. This year, based on recommendations from others, I decided to test out the easySim e-Sim for a 30 day US trip. Throughout my trip to Florida, the easySim product provided a strong 5g signal, rarely dropping to 4g. Competitively priced, I also found easySim more straightforward to install and use when compared to T-Mobile's product. One slightly unfortunate factor to note - the easySim is data only, you do not get a local mobile number with easySim. Unlike the T-mobile e-Sim which provides you with a telephone number - very useful to have so that you can make/receive calls across the US and leave as a contact number with people and stores that do not use WhatsApp.
