Go to Settings > Cellular > Add eSIM. Select 'Use QR Code' and scan the code sent to your email. Follow the on-screen prompts to label your new plan (e.g., 'Travel') and set it as the primary line for Cellular Data.
FUP is a network policy to ensure equal speeds for all users. If you use an excessive amount of data (e.g., over 5GB/day on an Unlimited plan), your speed might be temporarily reduced by the local carrier to prevent network congestion.
It depends on your plan. 'Single Country' plans work only in that specific location. 'Regional' (e.g., Europe) and 'Global' plans allow roaming across multiple supported countries without changing settings.
First, ensure 'Data Roaming' is turned ON for your SiMClaire line. Second, check that your APN settings are correct (usually automatic). Finally, try toggling Airplane Mode on and off to reset the network connection.
