Koko Mobile / Naka

I've been to several areas around London and Surrey beginning of July. Had my Koko Simcard with me in a iPhone SE. After deactivating flight mode, the network it connects automatically is "3 Three UK". As suspected following the LTE coverage list in the customer zone, it is only 3G no LTE. Tried also to log in to EE which worked like a charm. The Simcard got a Sim-Update and it changes the profile from the Israel Provider (for Switzerland) to polish Play Provider when roaming in UK.

I have two Numbers active in addition to the Jersey Number the card comes with. When calling from a UK mobile to Koko (it was a UK 3 card) there is a voice message announcing the rates will be higher than standard UK mobile phones. The Swiss landline DID seems to perform rock solid, I never had problems reaching the Simcard through DID.

When dialing the German mobile number it sometimes happens that I get a message, that the Koko Mobile subscriber is not reachable at the moment. This mostly happens, when I've called the Swiss DID, hung up and dialed the German number immediately. If you wait some time, it works. It looks like the German number is forwarding and thinks, the line is still busy. It never happened when dialing the jersey number directly.

Interestingly, all of my available Swiss and Austrian Mobile provider can reach the jersey number without any problems, no provider seems to block the Koko Mobile number. Compared to the UK number I've got with XXSim this is a big plus, because the XXSim UK number can not be reached with all providers (Salt CH, Skype)

I got to love my Swiss DID which is a little bit costly with CHF 5 per month, but I can route my own localphone.com numbers (landline numbers) at the cost of a landline call (0.01 USD) and even route my Swiss business mobile (which can only forward to Swiss and Liechtenstein numbers) free of charge. Combined with free incoming calls (outside EU/worldwide) on Koko Mobile, this is very attractive and makes Koko Mobile a no-brainer for me, compared to other roaming SIM cards with Estonian Mobile numbers (used XXSim before).

Totally right, +44 7937 for the SIM itself and +49 1577 for the German mobile number.

@kctopitz, I've been in Germany this afternoon and can confirm, that NAKA works on 02 up to LTE speeds. Haven't had any time to try other networks. Since EPlus and 02 merged their networks, it might have got slightly better with the coverage...

Thanks. Nice that you can connect on LTE. That could potentially solve the problems I've had with O2 MNVOs (no LTE access) in rural areas of Germany where I only get a 2G connection.

I still like the pricing and terms of DrimSim better. Too bad they don't offer an additional number.

I believe it's a UK Jersey number like Koko, but perhaps @wolfbln can confirm that.

I just figured out some "news". I have configured the SIP client to make calls with Koko-Moible at lower rates and discovered, that since about one week also incoming calls do work via SIP.

I've tried it only with my original UK Koko-Number. If my Sip-Client is connected, it rings on SIP (not via Simcard). When I disconnect Sip, calls do come in via Simcard.

This is great, as it works now the same way as Piranha Mobile did before! Can you guys try and confirm that it works on your Koko-Simcards too?

This is a good update.
I went to the web site and do not see anyplace to buy one.
You mention other brands that use NAKA in the background.

Are any of them advantageous for someone in the USA?
Do any have a free USA phone number?
Any to avoid?

The fact that it seems to make you happy with the SIP abilities vs. what Piranha used to do is encouraging.

Koko seems to be the best option if you want a US number, since you can add one additional number free. Higher call rates with the US number though. Discussed on page 1 of this thread. I don't think anyone here has actually tested it with a US number to confirm if incoming SMS are free on the US number.

I do have problems with incoming calls on my German mobile number as well as the Swiss DID. Swiss DID gives a recorded message, that the caller is not available at the moment (although the mobiles has full network coverage), the German mobile number rings 3-4 times, before a recorded message (about the same then on the Swiss DID) could be heard.

Koko does ring on first attempt, if I call the UK Jersey number. But that's about it.

Anyone else do have these problems? Please report back on which numbers you can/can not be reached at the moment.

Wrote to their support team on October 17th and got a reply that they are experiencing problems with their Swiss DID. Nothing changed since then...

Update on the incoming issue. Got a written email yesterday that told me, the Swiss DID is no longer available for Koko-Mobile. Calling the DID results in hearing a recorded message saying "This number is not assigned".

Unfortunately, they still charge for the number. Let's see, if they will refund the monthly fee for the Swiss DID...
