Purchase LTE router Watch that supports CA in Singapore

　I bought the "E5786" downlink mobile Wi-Fi router up to 300 Mbps launched in Singapore at the SingTel store in Singapore.

　In Singapore, "SingTel" introduced carrier aggregation and began to provide downlink services up to 300 Mbps in July 2014. E5786 is the first batch of terminals to support downlink up to 300 Mbps. In addition, corresponding to the terminal with a maximum of 300 Mbps in the downlink, smartphones will be put in turn in the future.

　The price of E5786 is sold in Singapore's SingTel store at S $399 (about 33000 yen) in Singapore's SingTel store and can be purchased without a contract.

　The SingTel store in Bugis Junction, where the author visited, did not have a display of mobile Wi-Fi routers and data communication cards. The staff in the store were shown the image of E5786 and told them, "I want to buy this with a single terminal." they will be led to queue at the cashier.

　Standing in line at the cashier, the clerk at the cashier also saw the image of E5786 and told him that he "wanted to buy with a single terminal". For some reason, he was taken to "ask the consultant" and went back to the origin. But after reconfirmation, you can buy it at the cashier. I bought my own terminal safely.

　When buying E5786, do you want to buy a prepaid SIM card? When asked "want to buy", he said: "the prepaid SIM that supports LTE is only nanoSIM and microSIM, and the regular SIM used for mobile Wi-Fi routers is only LTE incompatible." so I decided not to buy a SIM card.

　At this point, E5786, like other mobile Wi-Fi routers, believes that it uses regular SIM, but unexpectedly, E5786 uses microSIM, so even when using smartphones and SIM cards Don't worry about the size of the SIM card (if the smartphone is a microSIM terminal).

　Among the overseas mobile Wi-Fi routers supporting LTE, the E5776 and E589 produced by Huawei, the predecessor of E5786, use conventional SIM, so it is difficult to use SIM cards with microSIM smart phones, which becomes the bottleneck when using mobile Wi-Fi routers abroad. Therefore, using microSIM in E5786 is very helpful in situations where you also want to share SIM cards with smartphones that use microSIM.

　In addition, in the existing E5776, there are problems in the structure of the terminal or the difficulty of inserting and removing the SIM card, and using the SIM card conversion adapter may destroy the SIM card slot, but in E5786, it is easy to pull out the SIM card. Even if the SIM card conversion adapter is used, it can be safely used compared with E5776.

　What is interesting is that since SSID and password are always displayed on the monitor, it is difficult to take terminal photos and upload them to SNS (passwords cannot be hidden). Given the usual usage scenarios, displaying the SSID and password is easier to understand. I can understand this, but if the password can be set to hidden, thank you very much.

　As of the end of July 2014, the downlink maximum 300 Mbps corresponding area of SingTel is provided at Changi Airport, Singapore World Expo, Bugis station and other very limited areas, so the area that can benefit from the downlink maximum of 300 Mbps is limited. It is expected to expand to the entire Singapore region by the first quarter of 2015.

　Several speed tests are carried out at Changi Airport in the corresponding area of 300 Mbps downlink, and the results show that the downlink communication speed is 72 Mbps and the uplink communication speed is 21 Mbps. The maximum communication speed of E5786 is 300 Mbps, and the maximum downlink speed is 150 Mbps in the non-corresponding area of carrier aggregation, so it is impossible to assert that carrier aggregation is effective, but if the radio wave is in good condition, the communication environment will be very comfortable.

　To achieve high communication speed through the introduction of carrier aggregation, in addition to providing a maximum speed of 150 Mbps in KDDI downlink in Japan, DoCoMo also announced that it will be provided at a maximum downlink speed of 225 Mbps within 2014, and a higher speed mobile Internet can be used at home and abroad.
