The Phone You Travel With
A booking made from home lives in a thread on one phone, and roaming, a travel SIM or a new number can separate the traveller from it at an awkward moment.
Everything about a booking made from home is written down, which is its great strength. The date, the hour, the woman you named, the figure and the confirmation all sit in one thread. The weakness is that the thread lives on a phone, and phones do strange things when they cross borders.
The number problem
Many travellers buy a local SIM or an eSIM for the trip to avoid roaming charges. That is sensible for data, but it can change the number the phone presents, and depending on how the messaging app is set up, it can make the booking thread disappear from view or appear under a new identity. A traveller who booked from one number and arrives with another may find that the house does not recognise the messages, and the house may not be able to reach him.
The fix is to decide before travel. If you plan to change SIM, keep the messaging app tied to your home number, which many apps allow. If that is not possible, write to the house from the new number before the day, in the existing thread if you can or at the written address on the site with the date of the booking, so that the two numbers can be connected in advance.
The data problem
A phone with no data cannot receive messages, and a traveller who arrives with roaming off and no local plan is invisible until he finds hotel wifi. That is often fine; the room number message can wait until you are in the room. It becomes a problem only if something changes on the day and you need to be reachable: a question about the hour, or her message that she is on her way. Make sure data works on arrival, even if it is only for messaging.
The work phone problem
Travellers on business sometimes carry two phones and book from whichever is closer at the time. A booking made on a work phone and then looked for on a personal phone is a booking the traveller cannot find. Choose one phone for the thread, and preferably the personal one. It is also more discreet.
The battery problem
This sounds trivial and is not. The phone that carries the thread is also the phone that carries the boarding pass, the map, the hotel booking and the camera. By the evening of a travel day it is often at a few percent. On the evening of the booking, it needs to be charged and on, because she messages when she sets out and may need to reach you at the door. A phone that dies in the last hour is the one thing that can undo an evening that has been settled for weeks.
A new phone before the trip
Four weeks is long enough for a phone to be replaced. If yours is, make sure the thread comes across with the backup, and check that it has before the old phone is wiped. If it does not come across, write from the new phone with the date and hour of the booking, and the booking can be found and linked to it.
Discretion, on the device
A phone travels through airport security, sits on hotel desks and is sometimes handed to colleagues to look at a map. A booking thread with notifications that show message text on the lock screen can be read by anyone glancing at it. Messaging apps generally let you hide previews for a single conversation or for all of them. It is worth doing before the trip rather than after an awkward moment.
What to keep outside the phone
Copy the essentials somewhere else: the date and hour in Amsterdam time, the name of the woman you booked, the figure and the deposit, and the written address on the site. A line in the itinerary or a note in a password-protected app is enough, and it takes a minute to write before leaving home. If the phone is lost or dies, that line lets you reach the house from another device and keep the evening. The contact page gives the written address, and the booking thread entry explains why everything lives in writing.
