Things to note when buying a nice SIM or phone number

• Make sure the SIM as well as the phone number are not activated: An unbroken SIM does not necessarily mean the SIM is not activated. Check by calling the network switchboard to check your subscription or register for a postpaid subscription with a new SIM.
• Only pay in full when receiving the SIM: pay after receiving the SIM, do not pay in advance to avoid the risk of buying a junk SIM or not having the SIM delivered.
• Careful about the store that supplies the SIM: with rare and expensive SIM numbers, you can buy it at stores that sell directly or buy it on the official website.
• Needs to be a transfer contract with activated SIM numbers: the contract needs to have clear terms and the signature of the old owner to confirm that the old owner has transferred ownership to you.
