SMARTY prices from cdn.smarty.co.uk, checked 26 October 2026; SMARTY's options include calls as well as data. Where SMARTY charges by the day, we compare an eSIM with at least 1GB a day. SMARTY price guide (Aug 2026, linked from smarty.co.uk/roaming): EU band included up to 12GB a month (full allowance in Ireland), 60 consecutive days; outside the EU there are no roaming bundles, only pay per use from an out-of-plan balance at 2p/MB (Switzerland, Channel Islands, Isle of Man, Liechtenstein), 10p, 25p, £1 or £5 per MB by band. EU Roaming Data Pass (£3/1 day, £7/3 days) only lifts the 12GB EU limit, so no pack is marked headline. Plain data add-ons (1GB £1 to 15GB £14) work in UK and EU only and are left out.
