Verified Purchase(What is this?)
This review is from: Three Pay As You Go SIM Card with Adapters (Preloaded with 300 minutes, Unlimited Data and 3000 texts) (Accessory)
I bought one of these recently in order to use when in Ireland ("feel at home" with Three where you can use your Three mobile in certain countries as if you are in the UK so UK inclusive bundles, rates, etc). It was ideal for what I wanted and enabled me to keep in touch with family by text, phone or internet without worrying about running up an exorbitant bill. The sim card fitted well with the adapter and I was able to use it immediately.
