Samsung has warned that Galaxy Note 7 stock will be limited in Europe due to “unprecedented demand” for the device. The South Korean company says its new phablet will exceed its original sales forecasts “by some distance.”

Pre-orders for the Galaxy Note 7 first opened up to fans in the U.K. and Europe on Monday. Most carriers and retailers are promising late August to early September deliveries, but it seems those dates could start slipping soon.

Samsung has already delayed the flagship phablet’s release in some countries — including the Netherlands, Russia, Ukraine, and Malaysia — and now it is warning that there isn’t a whole lot of stock left for Europe.

“Market reaction, combined with extremely positive feedback from our carrier and retail partners, indicates that the Note 7 will exceed our original sales forecasts for the region by some distance,” said Conor Pierce, Samsung VP of mobile for U.K. and Ireland.

“As such, the number of preorder units will be limited due to the unprecedented demand.”

According to some reports, Note 7 pre-orders have already doubled those received for the Galaxy S7 and S7 edge combined. Samsung’s online store already says the device is “out of stock” in the U.K., though it is still on sale in other countries for now.
