NEC and NEC Platforms have released the strongest mobile router "Aterm MR04LN" that is compatible with all carrier frequencies. In addition to supporting LTE-Advanced with a maximum reception of 300 Mbps, wireless LAN supports 11ac (5 GHz) and a maximum of 867 Mbps, and in terms of specifications, it supports frequencies of all carriers, making it a product that any mobile user will be interested in. First, let's check the basic functions and usage of "Aterm MR04LN".

●Supported bands [Supported frequency bands] 2GHz/1.7GHz/1.5GHz/800MHz [LTE] Bands 1, 3, 8, 11, 17, 18, 19, 21 [HSPA+] Bands 1, 8, 9 [HSPA] Bands 1, 5, 6, 8, 9, 19 [WCDMA] Bands 1, 5 , 6, 8, 9, 19 [GPRS] GSM850, EGSM900, DCS1800, PCS1900

"Aterm MR04LN" is a mobile WiFi router that supports "dual SIM" that can be used by switching between two SIM cards, and is compatible with Docomo and Softbank (Ymobile) lines. Of course, it also supports docomo cheap SIM IIJ and Rakuten Mobile. It also supports international roaming in the LTE area of ​​overseas carriers such as AT & T and T-Mobile. In other words, the first advantage is that you can use high-speed mobile lines both in Japan and overseas.

The contents of the box are basic contents such as "Aterm MR04LN" main unit, battery, back cover, and micro USB cable.

Let's try it now. The SIM card installation slot is on the side, insert it until you hear a click sound. Be careful not to mistake the orientation of the SIM.

Next, set the APN. Most of the corresponding APNs are already registered, so just select the APN of the SIM you want to use.

●Services supported in Japan ・Docomo (mopera U) ・Softbank (EMOBILE LTE, Y!mobile share option) ・Cheap SIMs from Docomo, such as IIJ and Japan Communication

For details, check the list of devices that have been confirmed to work on NEC's product site. In Japan, services supported by docomo SIM are "mopera U" connection, and cheap docomo SIM and Softbank are also supported.

After setting the APN, check the upper left corner of the "Aterm MR04LN" screen. If you see LTE and up and down arrows, you're good to go.

Next, connect to your smartphone or PC. If it supports WPS connection, you can connect with "Setting" → "Simple wireless setting" → "WPS" on the home screen, so it's easy. If WPS is not supported, you can check the ID and password to connect from "Information" → "Terminal information" → "Wireless LAN information".

If you set the second SIM in the same way, from the home of "Aterm MR04LN" select "Shortcut" → "SIM You can use it by switching with one touch. By the way, it takes about 1 minute to switch SIMs, so I don't feel much stress, although I can't switch immediately.

Mopera U and DoCoMo , I measured the speed with IIJ. After all, docomo has a more stable speed, probably because it is crowded in the evening time.

If you want to use dual SIM conveniently in Japan, you can usually use the "WIRELESS GATE WiFi + LTE 480 yen plan" that allows unlimited use of 250kbps speed for 480 yen per month. Is it like using "IIJmio" that can use 3GB high-speed communication for 972 yen?

If you look at the compatible bands of "Aterm MR04LN", au's platinum band Band 18 (800Mhz) is also included, so it may be possible to connect. I would like to continue to verify this area! I would like to expect the addition of operation confirmation equipment in the future.
