I am thinking to buy a TP-link MR600 to use with my maxis 4g multi sim card. If connection stable, I'll subscribe to their 4g home unlimited package.

The modem cost around rm 500, just wondering if it will be overkill for my usage. I just hope to get something that has a higher chance to improve the stability and speed of my 4g signal in the house. Currently on my phone, occasionally it will drop to 3g or no signal at all.. randomly. When good, the 4g speed on my iphone can get up to 30mbps.

Any advice? should i spend a bit less for smthing simpler? or just get the MR600 for higher chance of making thing works?
