Fowarding US number to various SIMS

[eurouser]

I currently have 3 SIM cards and carry them all in separate phones simultaneously while traveling, currently in the EU, mostly Germany with a short trip to Poland coming up. I carry a solomo.de card, an Ortel card and a US AT&T card. I have found the redundancy necessary.

Rates a good, the two German SIMS average about 9 EU cents (per minute) for calls back to the US and incoming is free in Germany. Most outgoing calls to the US from outside Germany (still in the EU) need to be made via the callback feature on the solomo.de card. Incoming and outgoing runs about 29 EU cents.

Simple until I add the desire to use a US number to allow my contacts in the US to dial a local number for them to reach me. I have done this by purchasing two phone numbers from VoiceStick and forwarding each to one of my German SIMS. Now, since I want my US contacts to have one number to keep track of, I have a Google Voice number I forward to all of my US numbers at VoiceStick. When it is working, I call the Google Voice number and all three phone ring. It does work... sometimes.

Little gotcha's about how Google Voice stops ringing all numbers when one of them stops ringing can make calls stop going to all phones. For instance, if you have carrier that gives an off net unavailable answer immediately on the first ring, that intercepts all calls. If your voicemail on one of your SIMS picks up too quickly, the other phones stop ringing. With the connection delays on International calls this can be quite a problem. But worst is when one or more numbers malfunction, going straight to busy or otherwise going off hook before any of the SIM phones ring. The whole system fails and I have no indication it has without making test calls to my Google Voice number fairly often.

The most common point of failure for me has been VoiceStick. These guys have tried very hard to troubleshoot the issues I have had and I have goodwill toward them, so I feel bad about saying this, but 90% of the time I have found it is their system where my calls are not getting routed to my SIMS in a timely fashion or not at all. I have checked this by dialing my US numbers with them directly only to find there is an issue. The rates are quite good I think, forwarding from my US VoiceStick numbers to my German SIMS is 13 US cents per minute, making incoming calls while in Germany 13 US cents per minute total, incoming in the rest of the EU 29 EU cents plus 13 US cents or 55 US cents per minute. And I can always call my caller back at 29 EU cents per minute to save the 13 US cents if I want.

I pay a monthly charge of about $3 per VoiceStick number in addition to the 13 US cents for calls to the German SIMS.

So this deal is fine with me if I have reliable cell phone connectivity while traveling on the road most places in the EU. I can't be out of touch while moving around, so WIFI and wired connections are not much use to me. I need a reliable way to connect a US number to my German SIMS at a reasonable price. Since I am currently again having problems with my VoiceStick numbers I have decided I have no choice but to look at possible alternatives. Please suggest some for me. Thank you!
