Spoilt by 4G, I find Singapore's congested 3G far too slow. I'd wanted a 4G mobile Wi-Fi modem last year." categories: - Network tags: - 4G - Huawei - MiFi - mobile hotspot --- I was using the [Huawei MiFi E585](https://lesterchan.net/blog/2010/12/01/huawei-mifi-e585/) which I bought 4 years ago till the battery life decided to give up on me. The battery will go flat after about an hour of usage. On top of that I am spoilt with 4G because the 3G speed is way too slow in Singapore, due to bandwidth congestion. I wanted to get a 4G mobile Wi-Fi modem last year but it was still pretty expensive, but this year it seems the prices has drop quite a bit. I bought the Huawei E5372 4G Mobile Wi-Fi Modem from a reseller ([romz1983](https://forums.hardwarezone.com.sg/members/romz1983.479904/)) in HardwareZone Forums for **S$230**. If you are interested in getting it, check out the forum thread, WTS: Great MIFI sale from $90 Huawei E589 E5776 E5331 E5220 E5151 ZTE MF60 Wi-Fi Router. He offers other models as well. The mobile Wi-Fi modem is actually from [Telstra](https://www.telstra.com.au/) which is an Australia teleco that Huawei OEM for. It comes with 3,560mAh battery instead of the default 1,780mAh which gives you up to 10 hours of battery life instead 6 hours. It uses the normal SIM card instead of micro or nano SIM. If you have a SIM adapter, you can use it with it. Accordingly to romz1983, this is the first 150Mbps LTE mobile Wi-Fi modem that allows you to use SIM adapter. I am using micro SIM with a SIM adapter and it works fine. One of the reason for getting a mobile Wi-Fi modem instead of tethering from my phone is because tethering drains your mobile phone battery very fast (though you can keep it charging using a portable battery). I hope 2014 is the year where MacBook Pros/Airs will have a built-in SIM card slot! **Specifications** - 4G: Band 900/1800/2100/2600MHz - 3G: UMTS/WCDMA Bands 2100/1900/900/850MHz - 2G: GPRS/GSM/EDGE 850/900/1800/1900MHz - Speed: LTE Speed up to 150Mbps (Download) and 50Mbps (Upload) - Dimensions: 99mm x 62.2mm x 14.4mm (Width x Height x Depth) - Weight: 140g (including battery) - SIM Card Slot: Normal SIM (Micro SIM & Nano SIM can be used with adapter) - microSD Card Slot: Support up to 32GB - Wi-Fi: IEEE 802.11b/g/n - Wi-Fi Connected Devices: Up to 10 simultaneous device - Battery: 3,560mAh - Battery Life: About 10 hours [![Huawei E5372 - Box Front](https://farm8.staticflickr.com/7407/12377617635_75316ce837_c.jpg "Huawei E5372 - Box Front")](https://farm8.staticflickr.com/7407/12377617635_9e7ffc9c4f_o.jpg "Huawei E5372 - Box Front") [![Huawei E5372 - Box Back](https://farm4.staticflickr.com/3826/12377770473_64bb1f8ccc_c.jpg "Huawei E5372 - Box Back")](https://farm4.staticflickr.com/3826/12377770473_e8a147a12f_o.jpg "Huawei E5372 - Box Back") [![Huawei E5372 - Box](https://farm6.staticflickr.com/5512/12377769913_98acbcb1f0_c.jpg "Huawei E5372 - Box")](https://farm6.staticflickr.com/5512/12377769913_dce8cb1f07_o.jpg "Huawei E5372 - Box") [![Huawei E5372 - Box Contents](https://farm8.staticflickr.com/7434/12377617315_2f73d7d81e_c.jpg "Huawei E5372 - Box Contents")](https://farm8.staticflickr.com/7434/12377617315_ea9963bd07_o.jpg "Huawei E5372 - Box Contents") [![Huawei E5372 - Power Adapter](https://farm4.staticflickr.com/3749/12377769813_e1ac052375_c.jpg "Huawei E5372 - Power Adapter")](https://farm4.staticflickr.com/3749/12377769813_362926eeb3_o.jpg "Huawei E5372 - Power Adapter") [![Huawei E5372 - Battery Front](https://farm8.staticflickr.com/7421/12377617085_5625a1187e_c.jpg "Huawei E5372 - Battery Front")](https://farm8.staticflickr.com/7421/12377617085_be9dc8f527_o.jpg "Huawei E5372 - Battery Front") [![Huawei E5372 - Battery Back](https://farm4.staticflickr.com/3738/12378061874_6253c0ffc6_c.jpg "Huawei E5372 - Battery Back")](https://farm4.staticflickr.com/3738/12378061874_707084301e_o.jpg "Huawei E5372 - Battery Back") [![Huawei E5372 - Battery](https://farm8.staticflickr.com/7427/12377769453_65d7f538d2_c.jpg "Huawei E5372 - Battery")](https://farm8.staticflickr.com/7427/12377769453_8718666b6b_o.jpg "Huawei E5372 - Battery") [![Huawei E5372 - Front](https://farm8.staticflickr.com/7341/12378061934_247aeb29d9_c.jpg "Huawei E5372 - Front")](https://farm8.staticflickr.com/7341/12378061934_b0d9ee42c0_o.jpg "Huawei E5372 - Front") [![Huawei E5372 - Back](https://farm3.staticflickr.com/2819/12378061144_9649eaea11_c.jpg "Huawei E5372 - Back")](https://farm3.staticflickr.com/2819/12378061144_c71441c6d7_o.jpg "Huawei E5372 - Back") [![Huawei E5372 - Back Opened](https://farm4.staticflickr.com/3683/12377615705_4e553a470a_c.jpg "Huawei E5372 - Back Opened")](https://farm4.staticflickr.com/3683/12377615705_f7b07b3410_o.jpg "Huawei E5372 - Back Opened") [![Huawei E5372 - Back Opened (With SIM)](https://farm4.staticflickr.com/3716/12377616435_5672d7db8e_c.jpg "Huawei E5372 - Back Opened (With SIM)")](https://farm4.staticflickr.com/3716/12377616435_45859448d5_o.jpg "Huawei E5372 - Back Opened (With SIM)") [![Huawei E5372 - Micro USB Port](https://farm4.staticflickr.com/3752/12377616235_c556ff8d81_c.jpg "Huawei E5372 - Micro USB Port")](https://farm4.staticflickr.com/3752/12377616235_8d86c8e0a7_o.jpg "Huawei E5372 - Micro USB Port") [![Huawei E5372 - Menu Button](https://farm8.staticflickr.com/7313/12377616605_6b0ffc8cd1_c.jpg "Huawei E5372 - Menu Button")](https://farm8.staticflickr.com/7313/12377616605_2ca10e1262_o.jpg "Huawei E5372 - Menu Button") [![Huawei E5372](https://farm3.staticflickr.com/2885/12377768293_0b8c0200e4_c.jpg "Huawei E5372")](https://farm3.staticflickr.com/2885/12377768293_2ab020c2e9_o.jpg "Huawei E5372") [![Huawei E5372 - Switched On](https://farm8.staticflickr.com/7459/12377767343_1b1f38d3f8_c.jpg "Huawei E5372 - Switched On")](https://farm8.staticflickr.com/7459/12377767343_dfdd6f7af5_o.jpg "Huawei E5372 - Switched On") [![Huawei E5372 - Web UI](https://farm4.staticflickr.com/3804/12377914543_8f9690cf49_c.jpg "Huawei E5372 - Web UI")](https://farm4.staticflickr.com/3804/12377914543_66c8d8060e_o.png "Huawei E5372 - Web UI")
