Yes, GeoSIM works in 99.9% of GSM handsets. If you do not have an unlocked handset, we can supply one. Details HERE
GeoSIM uses the existing GSM networks, such as Vodafone, Orange, T-Mobile, O2, ATT, Telefonica, SFR, MTN, Digicell and many other GSM networks around the world. It will automatically select the strongest signal and lock on to it. You may find that as you move around, the network to which GeoSIM uses changes. This means you actually have a better service than the locals!
GeoSIM will operate on the following GSM Bands/Frequencies:
Due to the variety of network frequencies and systems around the world, it is stronly recommended at a Tri-band or Quad band mobile phone with 3G capability is used when you travel so that you are sure of getting a connection. GeoSIM is not responsible for lack of service due to an unsuitable handset.
In Japan and Korea you will need a 3G handset which
has UMTS/WCDMA 2100 functionality. You should ensure you have a suitable
handset for the region you are travelling to otherwise your GeoSIM (or
any other SIM) will not function. This is a handset requirement and not
a GeoSIM requirement.
US number recycling. If you have a dual number GeoSIM with a US number, your US number will be valid for 60 days. If you do not use your SIM within the US at least every 60 days, then your US number will be cancelled and "recycled". This is a US regulator requirement and not a GeoSIM condition. If your US number is recycled simply dial *160# to obtain a new US number. Unfortunately the same US number cannot be reasigned to your SIM.
SMS - GSM vs CDMA
GeoSIM works using the GSM system which is adopted in the vast majority of countries around the world by the vast majority of major networks. In some countries, the CDMA system is used by some networks. For example, some networks in the USA use the CDMA system.
SMS between GSM and CDMA networks is not always possible, although some networks may be able to translate between GSM and CDMA. Any failure of SMS delivery or receipt between a GSM network and a CDMA handset is not the fault of GeoSIM, but a symptom of two differing systems.
Your call credit will last at least 12 months from the time of purchase. See below regarding annual renewal fee.
Yes. A nominal annual fee of £4.99 + VAT is charged. This keeps your SIM active and call credit available provided that your SIM has also been used in the previous 12 months.
Unlike many Global SIM companies, we do not take unused call credit away from you if it is not used within a short period of time - some companies will take unused call credit from you after just 45 days.
One "Leading Brand" charges a daily usage charge of 39p and "Credit Holding Charge of £2 per month". This means that if you use your SIM, you are charged 39p per day (£142.35 per year!) and if you don't use it. £24 per year.
In line with our Clear Pricing Policy we do not hide this fee in higher call and call connection charges, or charge for non connected calls.
Our advice is to keep your SIM active by paying the £4.99 annual fee - it's very cost effective and means you won't lose any call credit.
Before the annual anniversary of your card, you will be contacted to see if you want to keep your GeoSIM active and keep your call credit. If you do, we will charge a £4.99 + VAT service access charge. This will keep your GeoSIM active and your call credit will roll over to the next year. Your SIM MUST also have made a chargable event in the previous 12 months. This could be a call, Text, or data session. If you decide not to keep your GeoSIM active your service will be permanently suspended by the carrier and any call credit cancelled.
You will be contacted by about 4 weeks, 1 week and on the due date, email reminding you to renew. The email will contain a link to the relevant page on our website so you can pay by by credit card or PayPal.
You can add call credit 24/7 via this website at our top up page or using Text2TopUp, a system which allows a top up request to be made by sending an SMS to our system. AutoTopUp is also available and allows you to Automatically top up your account when your balance gets low.

No. "Porting" of your existing number to GeoSIM is not currently possible, nor is porting your GeoSIM number to another provider. PAC numbers are not available for GeoSIM numbers.
GeoSIM 0770 and 07978 numbers are main land UK mobile numbers.
Calls to these numbers from a BT (British telecom) landline cost about 17p per minute during the day, 13p during the evenings and night and 8p at weekends.
The GeoSIM number range is also eligible for BT Friends & Family discounts which reduce the above prices by about 10%.
Most UK networks charge their "standard Rate" to call GeoSIM, which is normally between 10 and 40p per minute, but it does depend on your package you have with your provider. Please check with your service provider. We have no idea why some networks charge to call another UK mobile, but its probably for the same reason they charge high roaming charges!
NOTE: You can add local land line
phone numbers to your GeoSIM so that people can call you at local rates
or free of charge depending on their service provider. For more details
Please note that we try to keep up to date with other carriers tariffs, but they may change their pricing to call various number ranges, including GeoSIM numbers before we can update our web pages.
If you are a non UK customer, your network or carrier will probably charge you for calling a UK mobile. You need to ask your carrier or network what they will charge to make an international call to a UK mobile.
