So the voip application is completely independent of sim. If I set their voip account in my iphone without the sim inside the phone it will work on their voip under wifi.

yes it will work

This is not strictly true, the incoming calls whether the Sim is active and in your handset or not, will always be routed to the cheapest incoming route, if your wi-fi is on it will be routed trough to you via your VoIP application, which is always free to receive no matter where you are roaming. Only when you turn off wi-fi will it be routed via your normal GSM.

i'm not pretty sure you're right.. on my piranha sim when the simcard is active as well as the voip app, the incoming call always rings on the gsm...

no we are 100% correct, and the only way for you to test is to call your Sim number when you have Sim and wi-fi activated together, when you have answered your call check your account status, you will find that you have not been charged for the incoming call. Please make sure that you have a sound internet connection or it will revert to GSM incoming.

are you a piranhamobile employee?

will test this evening and let you know.

New great service from piranha!

OFF-LOAD CALLING

This service introduced by Piranha is the landline or mobile Call-Back (also known as Call Off-Load). The idea which prompted this feature is the fact that traditional Call-Back can be expensive in some countries where inter operator termination (IOT) costs apply, so instead of getting called back on the Piranha Sim, Piranha allows customers to be called back on a local landline or mobile. For example, a customer in India who would want to call Russia, is now able to request a Call-Back to their direct line at their hotel in India, Piranha then connects the call to the intended destination in Russia. The call is triggered using the users Piranha Sim, and is billed to the customer's mobile billing account.

Example:

a. Using Call Off-Load, calling from India to USA, landline or mobile, normal Call-Back call costs £0.56, making same call using Call Off-Load from landline or mobile costs £0.03.
b. Using Call Off-Load, calling from Pakistan to UK landline, normal Call-Back call costs £0.34, making same call using Call Off-Load from landline costs £0.05, from a mobile £0.07.

Call Off-Load Set-Up:

Making cheap calls using Call Off-Load:

Use your mobile to call as shown with the numbers *110* Call-BackDestinationNumber * DestinationNumber # Send.

a. Call-back Destination Number = number where the person initiating the call wants to be called.
b. Call Destination Number = number that the person initiating the call actually wants to call.
Once the landline or mobile rings at your destination, answer the call as normal, you will then be connected to the number you are calling.

uh that is neat, in order not to carry another calling card for this reason. thumbs up!

and the calling rates for this CallOff service are very very cheap, i suppose very close to their net rates.

Piranha users now have access to Call Forwarding.

i would not say very very, but in a good medium range to expect a reasonable to good voice quality.

you can even change the CLI to every number you wish to be shown to others.

if outgoing calls were charged per second (not per minute) , as some competitors do especially for calls within Eupean Union according to EU legislation , piranha simcard would be the perfect product.


A useful service for consideration would be CELL-ID .. to know the location of the simcard.
it's already introduced from rival simcard as ekit, travelsim, xxsim, camelmobile etc.
I believe is easy to set up as this service is based on google maps data...

Do you think they will ever get direct calling in the UK that would be very cool? I have been using them for a while now and find the service is very reliable.

gkeeper , i don't think so, at least soon.
if you desperately want direct calling (no callback) in UK you better have a camelmobile simcard

camel standard rates in UK: free incoming calls, eur.0,25 per minute for ALL outgoing calls, eur.0,49/mb data, eur.0,25 per sms worlwide or eur.0.09 to EU countries.
intranetwork rates (camelmobile to camelmobile) from UK costs eur.0,18/minute.
Calls from UK to EU countries are charged per second according to EU legislation, as well per second billing for intranetwork calls.


if you also like you can subscribe to the special voice bundle that includes also UK, which you get:

the first minute of outgoing call is charged according to standard rate (eur.0,25)
outgoing calls starting from 2nd minute – 0,185 EUR/min;
Bonus for incoming calls starting from 3rd minute – 0,02 EUR/min. credited daily.
charging is also per second

Cost of bundle: 2,50 EUR. charged once on activation, valid for 6months

Just noticed that I can setup call forward, I have now forwarded my piranha to my orange for when I am in the UK, saves me needing to carry to mobiles around, costs 5p per min.

Do you have a Data package with your Orange Carrier in the UK, if you do and you use a Smartphone, then why not download the VoIP app, this will save you more money and its always free to receive calls via the VoIP application (on all your Piranha numbers) no matter where you are. You can also ring out internationally at very low rates.

Can you give us the recommended voip application for iphone from the AppStore and let us know if nano sim to be used in new iphone 5 will soon be available to purchase.

1. We highly recommend the iSip VoIP application for iPhones, £3.99 from iTunes.
2. We have no current plans for the nano Sim, however any changes will be posted on the Piranha website forum.

the expansion of direct call (not callback) to much more countries will definitely have a positive effect to all your customers.

In a perfect world. Unfortunately it does not work that way.

I've used Groundwire with Pirahna and it works well with their clients.

Folks at Pirahna, a have two questions for you: (a) any plans for SMS forwarding?; or, (b) a client to allow you to text on an Android or iOS device over 3g?

Also, I see that you can set a different caller-id with your phone. How does one do that?

i set a different caller-id via contacting their customer service on their online chat.

Piranha VOIP on Samsung GS2
 

recently upgraded to Samsung Galaxy S2 from S (Vibrant), and the VOIP would not work (on Android ICS 4.04). Had to install Acrobits SIP on their recommendation, now it's fine.

I use the Acrobits SIP too, very satisfied with it.

piranha states in their forum that they'll launch a new voip application in the coming weeks.

No, we have stated that we hope to launch more apps in the next 8-12 weeks.

For the record, Acrobits and Groundwire are similar offerings from the same company. For $3 more, Acrobits offers a few extra features. I decided to be the "big spender."

problems in Iceland with Piranha
 

was just in Iceland a few days, and had problems with the Piranha sim. Only got data for a few hours in total, unclear why, I had all the settings right (and there was data on wife's phone using UK Orange sim). And the call back system for making calls was spotty, did not always ring back. Customer service said something about their servers there...

International Call Forwarding with Piranha
 

Just discovered the call forwarding service on Piranha works for international numbers - this is a unique solution, as far as I know, without monthly charges.

I've tried various things, google voice + Keku, tel3+ speed dial numbers, but all sorts of constraints prevent these from working. I just wanted people who dial my US cell to get forwarded to a UK or other local sim.

I just set my US cell to forward to the US Piranha number, and use the Piranha forwarding service to an international number, et voila. It was 6p/min for an Israeli mobile sim

Going to be in Canada later this week, and saw a Piranha warning re frequencies.
I'm using a Samsung Galaxy S2 (home is TMobile US network), phone specs are:
Networks Quad-band GSM world phone(850/900/1800/1900 MHz)
Data GPRS/EDGE/HSDPA/UMTS

I've used the phone before without problem in Canada for phone and data using native TMob sim card and also using Truphone. But if Piranha only works with Bell in Canada,
AWS 3G 1700Mhz/2100Mhz, is that a problem?
thanks for any help...

(also posted this on the Piranha FAQ board, but no response today!)

Piranha in Canada
 

so here is there response, apparently using Telus/Rogers again...

"we use Bell and Telus networks in Canada, you should have no issue using your handset for Data on either network. There is no price difference in networks. For best results please make sure your handset is set to Automatic search." Piranha Admin

I thought that the TMO's version supported 1900mhz HSPA as well.

Samsung I9100 Galaxy S II - Full phone specifications

My concern would be that you probably don't have 850mhz HSPA and could have spotty coverage.

The UK numbering range used by Piranha is assigned to Telecom North America (Telna). Does anyone know what the relationship is between Piranha and Telna?

Do they share the same platform and do they experience similar reliability issues as Telna did (or still does)?!

same product but i think piranha uses another telephone routing platform.

Hi I do not know all the answers to your questions, but I have used Piranha for around 4/5 months now and I have had no major issues with service on GSM or VoIP. I did try XxSim on my last trip, but that's another story.

Has anyone noticed?
 

It has an expiration of 420 DAYS!

And somehow a minimum balance of £1.00 is involved also.

They answered my question:

Sir, When posting information, please insure that you read the full terms and conditions and post the correct information, this is for the benefit of all.
The Piranha Sim only expires after 420 days of non use and only after the customer has been given 14 days written notice, if one call or SMS is made during this time the 420 day cycle starts again. Piranha expect the customer to maintain a balance of no less than £1.00 at all times. The information posted would suggest the card expires after 420 days regardless of usage.

Uh, no
 

Uh, no.

What part of implies "the card expires after 420 days regardless of usage"

to reiterate your fist post "Has anyone noticed"

"It has an expiration of 420 DAYS!"

you do not mentioned the fact that if the card is used once within this time the 420 day cycle starts again and therefore your post could easily be misinterpreted as expiry after 420 days, regardless of use.

So let me get this right as long as I use my card once in 420 days it will stay active, and I can then get another 420 days before it would become inactive again.

Sounds reasonable to me, my last Orange pay as you go sim was terminated in a lesser time than that, 259 days when I did not use it and they took my £25 balance.
