Things you need to know before buying a Slowakei eSIM

  1. Main 5G/4G frequency bands in Slowakei

Slowakei’s mobile networks operate on the following key bands: 4G (LTE) bands 1 (2100 MHz), 3 (1800 MHz), 7 (2600 MHz), 8 (900 MHz), and 20 (800 MHz). 5G networks use bands n1 (2100 MHz), n3 (1800 MHz), n28 (700 MHz), and n78 (3500 MHz). Ensure your device supports these bands for optimal performance.

  1. KYC requirements for eSIM activation

To activate a Slowakei eSIM, you must provide a valid passport or national ID for identity verification. Some providers may require a selfie or proof of address. Roami simplifies this process by handling KYC digitally during checkout.

  1. Fair Usage Policy (FUP) and data limits

Most prepaid eSIM plans in Slowakei have a Fair Usage Policy (FUP) that caps high-speed data after a certain threshold (e.g., 20 GB per month). Once exceeded, speeds may be throttled to 128 kbps. Always check the plan details before purchasing.

  1. Network coverage in rural and mountainous areas

While urban areas have excellent 4G/5G coverage, rural and mountainous regions like the High Tatras may have weaker signals. Telekom offers the best rural coverage, but it’s advisable to download offline maps as a backup.

  1. eSIM compatibility and dual-SIM usage

Most modern smartphones (iPhone XS and newer, Google Pixel 3 and newer, Samsung Galaxy S20 and newer) support eSIM. Slowakei eSIMs work perfectly with dual-SIM setups, allowing you to keep your home SIM active for calls while using data on the eSIM.
