The Sim card came in a standard credit card sized plastic holster from which it pops out. There were full instructions in English and other languages. To register the card you are directed to a Lebara website (which you can choose English). You are initially asked for your number, however, (unlike UK sims) the sim I recieved had no number on the sim, card, packing or instruction. I could activate it online but only after callng Customer services and obtaining my number (defeating the purpose of online activation). Great card but would be much better to include its own number on the sim - especially if your in a hurry.
