As someone who has used several of these international sim cards, 420 days seems quite generous. Assuming Piranha is still around after 420 days of course...LOL! I picked up piranha a few months ago, after I've had it with Telna. Have not had the chance to really use it outside the USA though. Besides the couple of test calls I have done on it. Their rates just seem too good to be true, especially in the Caribbean. Again, I have had several of these sim cards show very reasonable rates for most of these countries, but come to find out the sim would not work once one is on ground. Anyway, I always have a backup. For now, it's Ekit and Piranha as my international sims.

So far the Countries I have been in through work, the piranha sim has worked well. The counrties are as follows:
USA Canada South Africa Australia Singapore Thailand Germany France Ukraine I hope they are still around for a long time I do not want to have to go through the saga of finding another sim that works. |

The callback module doesn't seem to work right on many phones. Other than that, it is great. Telna (which shares some infrastructure with these guys) just started offering texting over the web and receipt of text messages that way. It would be great if an Android/iOS client was released that implemented these features.
Piranha is now offering an interesting unlocked Android phone. |

Also with all devices I have to use the SIM Toolkit for a call. The normal callback module don't work. |

My friend in Germany emailed tech support with the details. It was a Huwai Comet. I don't know what my other friends in Oz used. I had them dial *111*12125551212# and it worked, but it took a bit to figure things out.

I wasn't suggesting you guys did anything wrong. I was just suggesting that remotely troubleshooting an only moderately technically inclined person's problem from the other side of the globe introduced some complications.

received my SIM today
Well, I received my SIM today. [8 days to California from UK pre-Christmas.] You go online to activate it. Area code was local. Prefix is my city. Kind of weird using £s instead of $$. Rates US to US are as advertised. One can add £5.00 using PayPal on the website [& I did]. One can send SMS to it using US or UK phone numbers from web site.
Very pleased so far. |
what i dont like is the fact that they charge each callback. no matter if someone picks up or not. This can also be quite costy if you try to reach someone who hardly listen to his phone... Do they actually bill both legs right away or only the inbound leg first (as it was with the very first yackiemobile card)?

On a more positive note we will be reducing the call off load and call forwarding charges in the coming weeks by approximately 10%. |
Yes, its understandable but it makes the costs quite unpredictable. In that case i prefer to pay 1-2ct/min more but know when i get billed...

Of course everybody has to take his own decision - but for me this is definitely a no-go criteria for a SIM card. |

Piranha Mobile 3G on T-Mobile's refarmed 1900mHz band.
In case anyone is wondering, Piranha Mobile can and does operate on 3G on T-Mobile's refarmed 1900mHz band.

I am now in South Korea and the card is working good.

If you go to the web page and look up the rates it will show networks. In Spain, [I assume you can verify this] all 3 networks listed have the same rate. Is one of them preferred? Does it matter? |

piranha sim uses telna (telecom north america) infrastructure and product which i think has an agreement with O2-UK for the roaming interconnection |
Quote:
I had some family go over to London for the Olympics and Truphone was the SIM i gave them. Other than taking some time to register, it worked flawlessly. I did have to work with Tru as the per minute pricing that I was charged did not match the prices on the web site. They did refund the difference, but it would be nice to not have to do that step. |

Who/What is Telna??
Quote:
In the USA, Piranha uses Telna and T-Mobile for carriers. Until someone actually reports seeing 'Telna' as thie network on their cellphone, I would assume 99.9% of the time will be on T-Mobile in the USA. I assume that Piranha uses Telna to get access to the T-Mobile network. Probably much easier than dealing with T-Mobile itself. This is my understanding, but not verified in any way to be true. Thus, if anyone _knows_ with more certainty than idle speculation, I would love to stand corrected. If you go to:::Mobile World Live - Coverage Maps And then scroll down and click on United States and then scroll down to: >>Telecom North America Mobile Inc. (telna Mobile) You will see about all there seems to be available about Telna. Here is some more from Telna's website. Quote:
I know of no links between Telna and Piranha other than this network use. |

Commnet
Quote:
I was able to find six prefixes for Commnet in Arizona. Tucson in the 520 area code. 928 area code: PAGE, TUBA CITY, DILKON, KAYENTA, FT DEFIANCE. These in the 928 service near or in the Navajo Nation [also possibly the Hopi Nation. Page is outside of the Navajo Nation but on former land of the Navajo. All these prefixes serve small communities and one prefix is enough for them. Also, there are probably other cell providers in each. Coverage maps: Commnet Wireless |
what is actually the use of these very tiny mobile operators in the US that cover one or two corn fields? Is that more like a network for closed communication (like a petrol company or sth like that) or do they really seriously getting customers?

Mostly they are purchased like land to resell. Sometimes the theory is to make money from roaming revenues. Occasionally it is a small town that just wants service and the big guys didn't think it was worth it.
Remember that the US started with a bunch of these companies and they were bought out. We did not do like most of the EU and grant licenses nationally. The theory at the outset was that the smaller licenses holders would have a greater incentive to cover their little plot of coverage area. Until roughly 2000, most Americans had plans like the folks in Canada, Mexico, and India do where we roamed if we got 80k from our homes. Notice that Verizon Wireless holds a number of GSM licenses in the US even though they use the competing CDMA technology. In small towns where they have licenses, they will often through up "roamer nets" which are GSM networks solely designed to get roaming revenues from GSM visitors who travel through or visit these towns. The United States is geographically as large as the EU but when you get away from the coasts, we have a large areas of land with very light population density. There is an opportunity for investors to develop this areas for roaming revenues and eventually to sell to the big guys. Additionally, several years ago our Justice Department granted an antitrust waiver to the major U.S. carriers to develop roaming collectives for desolate parts of our country. ATT, Sprint, Verizon, and TMobile can agree to jointly cover a desolate stretch of a North Dakota freeway and each invest in the collective. Lastly, a small amount of the US carriers are actually Indian Tribal Governments who function as semi-autonomous/self-governing regions in the US. In addition to raising revenues from roamers, they may have an aspect demonstrating self-autonomy over practicality. I was looking at the Canadian list of small providers last night and there were a lot of tiny Canadian ones I never heard of. The idea of buying one of these to take advantage of Government mandated lower roaming rates is interesting. E.g. China Mobile buying the Artic GSM cooperative outside of Anchorage and letting China Mobile subscribers get FCC mandated domestic discounted roaming rates. |

Does anybody knows what the reason for this is? The Callback worked really good and the voice quality was also high. Sometimes I was not direct reachable over the US number. The caller had to try 3 or 4 times to reach me. The VOIP application worked for outgoing calls good with also a good voice quality. For incoming calls was the voice quality was really bad and I removed the VOIP application from my phone. SMS are only working outgoing. I' am not getting any incoming SMS. Only the SMS from the Piranha support are working. The prices are really good and I hope Pirnaha will be longer in business. |
SMS issues?
Quote:
Sending an SMS from Piranha's web site worked for both the US and UK numbers. |
