Lyca Mobile

T-​mobile on the cheap. If you don’t like T-mobile’s network then you won’t like these guys. If you’re not pressed over 4G and are so cheap it hurts you to even pay a monthly bill for a cell phone then this is probably your only option. This is the only reseller I know of that passes on significant savings. If you’re looking for customer service you won’t find it here. These guys don’t even bother to use an answering machine after hours. You’d think they’re out of business. Is this a problem? No, it’s just highly annoying. Is it a reason not to do business with them? Only if you require customer service.
All of the nasty reviews for this company are probably based on customer service and other things that these guys don’t offer. I haven’t actually taken the time to read the reviews but anyone giving a nasty review to this legitimate reseller obviously missed the whole point.
If you’re trying to port a number then Do NOT activate the number they give you. Once you get your SIM card then follow the steps to port your number over. Otherwise you’re going to be wanting to add a nasty review yourself for paying a month of service on a number you never wanted when it’s your own fault for not doing your due diligence.

SCAM/​RIPOFF!!! AVOID!!!
I bought some Lycamobile preloaded SIMs and the company (Lycamobile corporate) refuses to activate them or offer a refund or credit. They are the old SIMs, not the new «plus» SIMs. They have ‘discontinued’ them. What a scam! The company I bought the SIMs from offers no solution either, since Lycamobile won’t support them in doing so.

Have used Lyca for over a month here in San Francisco. Although I find the pricing to be excellent, you really do get what you pay for. Terrible customer service and we’re in the midst of a 2-​day voicemail downtime. Callers are unable to leave voicemail and users unable to access their voicemail.
Spent a solid 45 minutes on hold only to be given the complete runaround (despite acknowledgement of a system wide issue). When I asked to speak to a supervisor, I was put on hold only to have the call dropped… conveniently.
Buyer beware.
