Hi @Missscrawly
You cannot choose a start date for an iD Mobile Roam Beyond add-on. All Roam Beyond passes activate immediately upon purchase and cannot be scheduled in advance. Because of this immediate activation, iD Mobile recommends purchasing the add-on either on the day you travel (before you leave the UK) or after you arrive at your destination using local Wi-Fi
These Roam Beyond add-ons are data only. If you make traditional calls or send SMS messages, you will still pay standard pay-as-you-go rates, which can be expensive. To avoid extra charges, you can use apps like WhatsApp over your purchased roaming data to call and message home.
Hope this helps x
