One of the biggest problems for students going to the Czech Republic for Erasmus is choosing the right phone line and internet package . Students who activate roaming with their Turkish phone lines experience a bill shock within minutes. “The daily fee has gone up to 250 TL, never use it!” This blog analyzes all the experiences in student conversations and explains step-by-step the cheapest, fastest, and most sensible phone line options in the Czech Republic.

1️⃣ Why Using a Turkish Phone Line is Illogical

Most students try to activate their Turkish SIM card and use the internet during the first few days. However, roaming charges in the Czech Republic are quite high.

✔ Average roaming costs.

• Vodafone. ~250 TL per day.

• Turkcell. ~279 TL per day.

• Turk Telekom. The non-application package is much more expensive.

Therefore, using the internet with a Turkish network is definitely not sensible .

Türkiye line only.

• Receiving SMS

• Simply keeping it open is enough for bank verification.

2️⃣ The Cheapest and Most Recommended Phone Line by Students in the Czech Republic: Tesco Mobile

Tesco Mobile is the cheapest mobile phone line recommended by 80% of students. It's both affordable and offers a wide range of packages.

The advantages of this package.

• Affordable price

• Most parts of the Czech Republic have good reception.

3️⃣ Other Popular Operators

Besides Tesco Mobile, there are three other major operators. However, their prices are higher than student packages.

4️⃣ The Most Sensible Settings for Students Using Dual SIM Cards

Most students participating in the Erasmus program use dual-SIM phones. This setup prevents line interference and resolves noise issues.

✔ The best way to use it.

• Turkish line. Only calls and SMS should be enabled.
