speeds are frequently slow, especially during lunchtime.

Pocket Wi-Fi also maintains very stable communication speeds compared to Prepaid SIM cards, although speeds may decrease depending on congestion.

Since the use of Prepaid SIM cards is for a fixed period of time, if there is a sudden increase in the number of users or data traffic capacity, the speed quality may be poor due to the difficulty in adjusting the bandwidth for the Prepaid SIM card. The SIM used in Pocket WIFI increases the bandwidth to match the line being contracted, so the quality of communication is less likely to deteriorate than with a Prepaid SIM card.
