For your Truly Roaming eSIM to function seamlessly in Barcelona, your smartphone must be unlocked. A locked phone is restricted to its original carrier's network, preventing it from connecting to the local Spanish networks like Movistar, Orange, or Vodafone that Truly Roaming utilizes. Before purchasing your eSIM, confirm with your home carrier that your device is unlocked. This crucial step ensures you have day-one connectivity for all your remote work and travel needs without any unexpected hitches.
