Unlock your cell phone so that it can work with any GSM network, in your home country, or anywhere else in the world.

As long as your phone uses the same frequency bands, it should be able to work on any other GSM network after you have unlocked it.

Unlock your Siemens GSM Cell Phone Use Your GSM phone on any compatible network
	If you have a GSM cell phone from Siemens, such as the SL55 you see pictured here, we can unlock it for you.

The chances are that your Siemens GSM phone was supplied to you in a 'locked' condition, restricting your ability to use SIMs from other suppliers in your phone.

Here's how to simply and quickly unlock your phone so you can use it with any GSM service provider and SIM, anywhere in the world.  This can both save you money and enable you to use wireless services with better coverages in the areas you travel.

More information about unlocking

Please refer to our Unlocking FAQ and also the extra information on our Nokia Unlocking page if you'd like to understand more about what unlocking is and how it works.

But the chances are, because you're here and reading this, you already know much of what you need to know!

How to Unlock Your Phone

At present, as well as unlocking Siemens phones, we are able to provide unlocking codes for some Motorola phones, plus most Nokia and LG phones, many Sony Ericsson phones, Blackberry PDA/phones, the Treo 600, 650, 680 & 750 PDA/phone, most models of Samsung phones and the Apple iPhone.

Your Siemens phone needs to be unlocked in person by us, using special software and special hardware.

Neither we nor any other companies (as far as we're aware) can unlock these phones simply by giving you a code to key into your phone yourself.  We can do this for Nokias and some other brands, but not for Siemens phones, which use a different form of locking.

You Can Trust Us

Our unlocking service has been positively featured on CNN, and written up in many places, including the Washington Post, the Philadelphia Enquirer's Consumer Action column, and the Clark Howard Consumer Action Center.

We are not a 'fly by night' scam outfit.  Look at everything on this site - there are several hundred pages of content, dating back to 2001.  We have a major internet presence, and years of credibility.

Here's a page of testimonials from satisfied customers.

We're located just out of Seattle, very close to Microsoft, at 17321 NE 31st Ct, Redmond WA 98052 (but please note our ship-to address is in Kenmore).

We're a Paypal verified member (this link will take you to a Paypal page that confirms our status), with an account dating back to 2000 and over 2500 successful transactions recorded.

We've unlocked thousands of phones, have been trading for years, and have been well written up by independent reviewers.  We're experienced, skilled, and reliable.

Why Choose Us

Other companies also offer unlock services, some with the same mail in type service we provide, and others that will ship you special unlocking software and cables and allow you to unlock your phone at home yourself.

A mail in service is best, because that saves you from having to become a cell phone technician.  We have the skills and experience to unlock your phone, and we have more advanced equipment than is sold to you for an 'at home' unlock.  Best of all, we test our unlocking with our six way unlock test - something you probably can not do yourself.  You don't want to discover, the first time you try a foreign SIM in a foreign country, that the unlocking didn't properly work for all types of SIMs!

When you get your phone unlocked back from us, there are no surprises and no problems.  You can confidently use it, everywhere.  This is why you should choose us.

How Long Does it Take

We have two service options.  With our regular service, our promise is that we'll unlock your phone and have it on its way back to you within 24 hours of receiving it.  We send your phone back to you (to US and Canadian mailing addresses, only) via USPS First Class Mail, with Delivery Confirmation, insurance, and online tracking for your reassurance.  If returning to an international address, we send via Air Mail.

If you're in a hurry, or if you do not have a US postal address, our Express service may be better for you.  We'll turn your phone around the same day we receive it, and if there is sufficient time between when a courier delivers it to us and their cut-off for collecting packages, we'll have it shipped back to you that same day.  This could mean that there is less than 48 hours from when you courier your phone to us to when you receive it back again.

Obviously you can choose any speed of service you wish to get your phone to us.  In most cases, we recommend simple USPS Mail - it is reliable, convenient, reasonably fast and inexpensive.

Note - assuming your phone currently uses an AT&T, Cingular, or T-mobile SIM, you don't need to send your SIM with the phone, so if you have a spare phone, you can use your SIM in that phone while this phone is being sent to us for unlocking.

Our Guarantee - Six Way Test

We test every phone we unlock, using three different SIMs - the SIM you already had in your phone, a SIM from a different US wireless service provider than that which had locked your phone, and one from an international wireless service provider from Europe (the costs of the international calls are on our dime), to confirm your phone has been fully unlocked.  In each case, we both make a call from your phone and place a call to the phone, to ensure 100% functionality in all possible scenarios.

Assuming that your phone tests as working when it is first received, we guarantee that it will be fully unlocked.  If we can't confirm that your phone has been unlocked and works perfectly, we'll return your phone (of course!) and fully refund your money.

You don't have to worry if your phone has been correctly unlocked or not.  Our guarantee and testing gives you 100% confidence.

Phone Unlocking - Science and Art

When we first started unlocking phones, back in 2003, the phones were very much simpler, and so too was the unlocking process.  All Nokia phones could be reliably unlocked with a simple $5 code, and just about all other models could be easily unlocked with equipment we had in-house, and for which we charge(d) $25.

In the five years and more since then, the 'state of the art' has evolved enormously.  Not only do phones have a lot more fancy features for their users to enjoy, they often have much more complicated locking procedures, too.

Nowadays we never really know if we can unlock a phone until we see it.  Within a single model phone, there may be many different versions of firmware, some which can be easily unlocked, and some which can't, and some of which are specific to one wireless company, and others specific to others.

The appearance of a phone model on our list no longer guarantees that we can unlock it.  It means, instead, that most of the time, we can probably unlock it.  Sometimes we can't, and sometimes we have to get special third-party extra services, at extra cost which we pass on to you if you authorize us to do so.

Please understand, we'll do the best we can, to get your phone unlocked as quickly and inexpensively as possible.  And if we can't unlock your phone, we'll of course return it to you and fully refund you the fee you originally paid.

Special Offer :  Recommended Accessory for your GSM Phone

This is a SIM card Reader/copier/backup device.

This backs up and copies the phone book data on your SIM card. This means if you lose your phone, you don't lose all your phone numbers. If you change from one wireless provider to another, you can quickly copy all your phone book with this unit from one SIM to the other. If you have multiple SIM cards (eg a US card, a global roaming card, and some country-specific pre-paid cards), you can copy your phone book to all these different SIMs.

This $19.95 unit can be purchased for $17.45, plus free shipping when purchased in conjunction with any Siemens phone unlock service.

Here is a review of the SIM reader/copier/backup unit.  An opportunity to purchase it at a discount will be offered to you when you click the 'Agreed' button below as part of purchasing your unlock code.

Notes

Any delays with international shipping due to potential Customs problems, lengthier shipping times, variable and expensive shipping costs are all at your risk, and if we need to pay any extra Customs fees upon receiving your phone, you will need to send these extra fees to us.

Note that we can not be responsible for problems if the address you give us, above, is incorrect.

Terms and Conditions

We test your phone before and after unlocking it.  If your phone does not work properly when first received, we will return it to you, locked and unrepaired, and with no refund.

Phones are returned with delivery confirmation service and $100 of insurance cover in the US.  Additional insurance is available at a cost of $2 per extra $100 of cover.  Delivery confirmation and insurance is not offered on international shipments unless sent by courier.

In all circumstances and situations, our liability will at no time exceed that of refunding you your fee.
