Is anyone still using their Koko-Mobile SIM or any other Naka SIM? I am interested in getting a Koko SIM and asked them a question via e-mail and their support form on the website and never got a response.

I encountered that they silently slashed all other incoming numbers beside the original +44. There was a preferred rate going along with the German number, which got cancelled too.

Not sure what's happening at their end. Service works fine, but waiting one week for a service reply as well.

As a non-customer, I emailed them last year with questions about additional numbers. Never got a reply. If a company doesn't reply to people who are potentially interested in giving them money, that's a big enough red flag in my opinion to never give them money.

Still using my Koko Mobile sim card as a secondary sim in a rugged phone. In the USA, it will work on AT&T (my primary sim card is using a T-Mobile reseller called Mint)...no need to constantly top up the Koko card like a domestic prepaid AT&T MVNO.
It works fine when I am in Bermuda by USSD dialing. Other mobile alternative there were VOIP using a SkyRoam mifi device.
My primary need for Koko is really a backup sim that can use AT&T in the USA but also can roam in countries my primary sim doesn't work in (like Bermuda).
Also my interest in Koko is really for voice and SMS text messaging, since I can get data cheaper domestically or internationally through other means.
Like the switchable profiles and the USSD dialing capability.

My main reason for picking up a Koko sim card was the Piranha debacle...couldn't wait for Piranha to switch from Telna to Jersey Telecom as a background provider. The 2 Piranaha cards were eventually replaced, and now are used in emergency phones for my elderly parents.

Having problems with my Koko card.
Can't register sim on AT&T USA other than emergency calling. Also having trouble switching the country profile setting. Tried in two unlocked phones. Filed a trouble ticket and will see if they respond and fix the issue.
Not a JT issue because I swapped the Koko for a Piranha sim chip in my smartphone and Piranha works fine on AT&T.
Also noted that AT&T USA prices are up for Koko but down for Piranha.
Piranaha was USD$.10/minute and is now USD$.06/minute.
Koko was CHF.09/minute and is now CHF.13/minute (CHF and USD are almost on par).
Even if Koko fixes the problem I will likely switch back to Piranha because their prices are currently better in the countries where I need it most.

Sorry to hear your problems @gadgetken. I've been in China last week of August with Koko Mobile and had no problems with Network. Automatic Network search as well as Sim Kit Profile change worked like a charm, even had 4G Data in China. Only hassle was, that incoming calls were not 100% stable. I believe this is because the SIM card didn't manage the change between 4G and 3G properly. Beside that, the Simard performed rock solid and Data worked like a charm all week long. Even WhatsApp Calls and VoIP Calls through Data worked perfectly.

Initially, the SIM card only registered on EDGE Network, wrote a Email to them and got a answer within hours...

@bourbonkiller glad Koko worked OK for you in China.

Still having issues with Koko service in USA. Chip will work for LTE data in USA on AT&T but no calls or text will function. I'll just use up the remaining balance on some youtube music videos in a flip phone, and then cancel the card. Worked fine for several months but I can't depend on it now.

Not a big deal because I'm just swapping a Piranha card for the Koko card in my dual sim smartphone. Both have a JT back end but Piranha gives me voice and text in the USA.

Don't really need either Koko or Piranha for data because I can get that off a US T-Mo reseller sim called Mint, an AT&T postpaid mifi device with unlimited data, a Sprint/Karma mifi device or a SkyRoam cloud sim mifi device.

Is your PiranhaMobile sim still working in the USA? Can't receive calls on mine at all. The support person responded that they are checking with the roaming partner.
