Things you need to know before buying a Ungarn eSIM

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

Ungarn’s mobile networks operate on the following key bands: 4G LTE: Band 3 (1800 MHz), Band 7 (2600 MHz), Band 20 (800 MHz). 5G NR: n78 (3500 MHz) – primary band for high‑speed 5G, n1 (2100 MHz) – used for wider coverage. Ensure your device supports these bands for optimal performance.

  1. KYC requirements for eSIM activation

To activate an eSIM in Ungarn, you must provide a valid passport or national ID. Some providers may require a selfie or proof of address. Roami simplifies the process by handling KYC digitally during purchase.

  1. Fair Usage Policy (FUP) and data limits

Most Ungarn eSIM plans include a Fair Usage Policy (FUP) that caps high‑speed data after a certain threshold (e.g., 20 GB per month). After exceeding the limit, speeds may be throttled to 128 kbps or 256 kbps. Check your plan details before heavy usage.

  1. Network coverage in rural and remote areas

While urban centers like Budapest, Szeged, and Miskolc enjoy excellent 5G coverage, rural areas (e.g., parts of the Great Plain or northern mountains) may rely on 4G or 3G. Yettel and Magyar Telekom offer the widest rural coverage. Check coverage maps before traveling to remote regions.

  1. eSIM compatibility and device support

eSIM is supported on most modern smartphones (iPhone XS and newer, Google Pixel 3 and newer, Samsung Galaxy S20 and newer). Ensure your device is unlocked and eSIM‑compatible. Roami provides a QR code for instant activation.
