Duplicate notifications regarding Passport roaming plus. One says I'm in Greece, the other Turkey.

I'm holidaying in Kos, one if the Greek Islands and I have received a text confirming my Passport roaming plus charge of £2 per day, however I keep receiving a duplicate text saying I'm also in Turkey? Will I be charged twice?

Possibly, so make sure your device only connects to a network in Kos because accidental roaming can occur if you are close to a border.

As @caesarome indicates, given the Turkish mainland is only a few miles away, it's quite possible that a phone could attach to a stronger signal from there rather than a weaker one from a partially obscured mast on the island itself.

Fortunately in this case Turkey is one of the rare non-EU destinations which also has £2 roaming, so the potential damage is very limited: some cross-border connections can end up consuming data at several pounds per megabyte.
