Kyrgyzstan and Uzbekistan share a border through the Fergana Valley, commonly crossed by travelers combining Osh with Uzbek destinations in the valley, requiring separate data plans for each country.
Quick answer: A separate eSIM or local SIM is needed for each country. Your phone switches networks automatically at the border in most cases, but data plans don’t carry over between Kyrgyzstan and Uzbekistan.

The border crossings through this shared valley region see your phone switch networks automatically in most cases — confirming your connection once across avoids any confusion.
Why you need separate plans for each country
Kyrgyzstan and Uzbekistan require separate data plans — an eSIM covering only Kyrgyzstan won’t work once you cross into Uzbekistan, and vice versa.
Combining Osh with Uzbek Fergana Valley destinations
Many travelers pair a visit to Osh with destinations across the border in Uzbekistan’s portion of the Fergana Valley — the Osh guide covers this gateway city specifically.
Setting up your Uzbekistan connectivity before crossing
Installing a Uzbekistan eSIM while still in Osh, with reliable WiFi or data available, avoids any complications trying to set up connectivity right at the border — the install eSIM guide covers the equivalent process for your Kyrgyzstan eSIM.
Coverage immediately after crossing into Uzbekistan
The area just across the border maintains generally workable coverage, easing the transition into the country, similar to the pattern seen at the Kyrgyzstan-Kazakhstan crossing further north.
Choosing a network in southern Kyrgyzstan before you cross
Confirming solid coverage on the Kyrgyzstan side before your crossing helps ensure a smooth transition — the mobile internet overview covers network comparisons for this southern region.
