As a tourist visiting Turkey for a short-term visit, a prepaid mobile plan is generally the best choice. Prepaid plans allow you to pay for the minutes, texts, and data you use, with no long-term commitment required. This is ideal for tourists who may not need a mobile connection for an extended period. Prepaid plans are often more flexible, allowing you to add additional credit as needed. On the other hand, postpaid plans require a contract and may come with additional fees and charges. Additionally, postpaid plans may not be a viable option for tourists who do not have a Turkish credit history or residency permit. Overall, prepaid mobile plans are the most convenient and cost-effective option for tourists visiting Turkey.
